LORRI is a narrow angle (Field Of View, FOV = 0.29 degree square), high resolution (5 microradian/pixel), telescope. A two-dimensional (2-D) CCD detector, with 1024x1024 pixels (optically active region) operates in standard frame-transfer mode. LORRI can also perform on-chip 4x4 binning to produce images of 256x256 pixels. LORRI has no color filters and so provides panchromatic imaging over a wide bandpass extending approximately from 350 nm to 850 nm. The common data product is a 2-D image of brightnesses that can be calibrated to physical units once color spectrum information is known. Refer to DOCUMENT/SOC_INST_ICD.* for more detail. During the Pluto Charon Encounter mission phase starting in January, 2015, there were several sub-phases: three Approach sub-phases, (AP1, AP2 and AP3); a CORE sequence for the Pluto flyby on 14 July, 2015 (Day Of Year 195), sometimes also referred to as NEP (Near-Encounter Phase); three Departure sub-phases (DP1, DP2, DP3); a Transition sub-phase closing out the Pluto Encounter mission phase ending in late October, 2016. For this final LORRI delivery for the Pluto mission phase, this data set includes the Approach data plus all CORE, Departure and Transition sequences' data downlinked through the end of October, 2016, including observations of Trans-Neptunian Object (TNO) 15810 Arawn (1994 JR1) and a low-resolution ring search taken in November, 2015. Transition activities in 2016 include observations of several KBOs and a calibration campaign. This dataset includes (1) Non-Critical and Critical Optical Navigation (OpNav) observations; (2) Hazard observations; (3) Observations of Pluto, Charon, Nix, Hydra, Kerberos, and Styx during Approach; (4) Pluto Encounter observations, from the day before and the day of encounter; (5) Departure observations of Pluto; (6) Departure and Transition observations of TNOs and calibration stars. Optical Navigation images, identified by NAV in the observation name, were taken regularly up until 2 days before closest approach. This dataset also includes three OpNav images from 2 days after closest approach. Hazard observations were taken in order to perform a detailed search for any objects that could only be seen as the spacecraft neared the Pluto system. Sets of images were taken about every two weeks starting two months before closest approach. Each set had 8 images, with a mosaic of 4 images at two different roll angles. Approach observation objectives were to search for changes with pan imaging over multiple rotations, perform satellite photometry to further resolve the orbits of Kerberos, Styx, and possible other bodies, and image Nix and Hydra. Encounter observation objectives were to obtain maximum resolution imaging of the entire surface of Pluto and Charon at regular longitudinal intervals for cartographic knowledge; to observe Pluto and Charon at a small (12-30 degrees) solar phase angle to support phase integrals; and to obtain regional stereo images of Pluto for stereographic mapping at the highest possible resolution, which is essential for understanding the relief of features on Pluto, and understanding the magnitude of geologic processes and the origin of geologic features. Transition observation objectives were to obtain imaging of several KBOs including a light curve sequence of 15810 Arawn, and to execute a post-Pluto calibration campaign to feed back into the calibration of encounter data. Every observation provided in this data set was taken as a part of a particular sequence. A list of these sequences has been provided in file DOCUMENT/SEQ_LORRI_PLUTO.TAB. N.B. Some sequences provided may have no corresponding observations. For a list of observations, refer to the data set index table. This is typically INDEX.TAB initially in the INDEX/ area of the data set. There is also a file SLIMINDX.TAB in INDEX/ that summarizes key information relevant to each observation, including which sequence was in effect and what target was likely intended for the observation. Version ======= This is VERSION 3.0 of this data set. The TARGET_NAME values were expanded and made more consistent across all instruments with version 3.0 of the data set. General statement about data set versions after V1.0 ---------------------------------------------------- The pipeline (see Processing below) was re-run on these data for each version since the first (V1.0). That will typically change only the FITS headers but not the FITS data of raw data sets. In some cases this may change the calibration because the calculated geometry of an observation has changed. See data set version-specific sections below for significant exceptions to this general statement, i.e. changes to pipeline processing, calibration processing, and data delivered. An all-instrument Calibration Campaign occurred in July 2016. For all instruments, calibrations were updated as of April 2017 which changed the data in the calibrated data sets. Calibration changes are described in the data set version-specific sections. Note that even if this is not a calibrated data set, calibration changes are listed as the data will have been re-run and there will be updates to the calibration files, to the documentation (Science Operations Center - Instrument Interface Control Document: SOC_INST_ICD) and to the steps required to calibrate the data. LORRI updates for Pluto Encounter Data Sets V3.0 ============== This P3 Pluto Encounter dataset release includes all data from the previous two Pluto deliveries and adds data that was downlinked from 1/31/2016 through 10/31/2016. This dataset completes delivery of all data covering the Pluto Encounter and subsequent Calibration Campaign. This dataset contains data from the Pluto Encounter timeframe as well as two ring search observations and imaging of the KBO plutino JR1 in November of 2015.

There were minor changes to the level 2 LORRI calibration process, as well as to the LORRI calibration constants for the final Pluto P3 PDS delivery. The process change involves gap removal during calibration. Files with gaps come in many flavors, depending on where the gap lies within the image. This update recognizes some additional possiblities, mainly that the gap might be close to the bottom or top of the image (and therefore the previous algorithm would fail because it filled the gap with median pixel info from both above and below the gap). The new algorithm will take the info from one side of the gap exclusively, when appropriate. As of V3.0, targets for some stars and radio sources have been updated so that the TARGET_NAME keyword in the label is accurate and more descriptive than only STAR or CALIBRATION. However the user should confirm that targets from the data FITS files, if applicable for a given instrument, match the label name, as there are a few instances where the FITS keywords for TARGET, SPCCBTNM, and PNTMTHD are not accurate. The simplest way to check is to instead look at the RA and Dec in the keywords SPCBRRA and SPCBRDEC in the FITS file. This issue mostly only occurs with star targets. LORRI updates for Pluto Encounter Data Sets V2.0 ============== This P2 Pluto Encounter dataset release provides updates to the Pluto dataset between P1 (data on the ground by 7/31/2015) and P2 (data on the ground by 1/31/2016). This dataset contains data that may have been downlinked with lossy compression initially and now has been re-downlinked losslessly. Lossy data from P1 has been regenerated to increase the number of flagged bad pixels in the quality map. All liens from the initial Pluto delivery have also now been resolved. This dataset contains data from the Pluto Encounter timeframe as well as two ring search observations and imaging of the KBO plutino JR1 in November of 2015. The additional observations are listed below: Obs. Name (Request ID), Obs Date, Downlink Start, Downlink End, Obs.

data processing pipeline on the Science Operations Center (SOC) at the Southwest Research Institute (SwRI), Department of Space Operations. This SOC pipeline assembled data as FITS files from raw telemetry packets sent down by the spacecraft and populated the data labels with housekeeping and engineering values, and computed geometry parameters using SPICE kernels. The pipeline did not resample the data. Calibration =========== Detailed information about calibration of LORRI images is available in the SOC Instrument Interface Control Document (ICD) in the DOCUMENT section of this data set. The LORRI calibration will only be briefly summarized here; refer to the ICD for details about what is summarized here. N.B. The units of the RDR image data are calibrated Data Number (DN); responsivity factors are provided in the PDS label and FITS headers to convert the calibrated DNs to physical units; the factor to use is dependent on the target scene spectrum. Refer to the ICD and other LORRI documentation [CHENGETAL2008], [MORGANETAL2005] for more detail. Note also that some versions of [CHENGETAL2008], including the published version, have an error in the units of its Figure 9 ordinate. The PDS keyword PROCESSING_HISTORY_TEXT has been provided in each PDS label for calibrated data file with details of the parameters used or calculated and of the calibration files used in the calibration process. The responsivity factors mentioned in the previous paragraph are included there. The calibration of LORRI images involves all of the following steps in order: 1) Bias subtraction 2) Signal linearization 3) Charge transfer inefficiency (CTI) correction 4) Dark subtraction 5) Smear removal 6) Flat-fielding 7) Absolute calibration (DN with scene-dependent radiance divisors) Ground testing has demonstrated that the linearization, CTI and dark subtraction steps are not necessary i.e. the output from the Bias subtraction step may be passed directly to Smear removal step. In addition, the calibration procedure calculates the error and a data quality flag for each pixel and includes those results in the calibrated data product as additional PDS OBJECTs (FITS extensions) appended to the main OBJECT with the data image. The quality flag PDS OBJECT is an image of values of the same size as the main IMAGE product, with each quality flag pixel mapped to the corresponding pixel in the main product. A quality flag value of zero indicates a valid pixel; a non-zero value indicates an invalid pixel. Each quality extension pixel value is an accumulated sum of individual quality flag values. The list below contains the quality flag value associated with each condition: Quality Flag Value Quality Flag Description 0 Good pixel 1 Defect in reference deltabias image (0 or NaN) 2 Defect in reference flatfield image (0 or NaN) 4 Permanent CCD defect (e.g. dead pixel) * 8 Hot Pixel identified in hotpixel map * 16 Saturated pixel in level1 data (A/D value of 4095) 32 Missing level1 data ( assume fill value of 0 ) 64 unused at present Note that for windowed products, all pixels in an image are not returned in the downlink telemetry. In the raw data, the pipeline sets such pixels to zero DN (Data Number); the calibration processes those zero-DN pixels as if they were real raw values, but also flags them as missing data in the quality flag PDS OBJECT (FITS extension). Displaying such images using an automatic stretch (contrast enhancement) may result in a confusing result with the majority of the displayed image appearing as an inverse of the calibration (calibration of zero values); therefore the quality flag PDS OBJECT should always be checked when looking at these data. Ongoing in-flight calibration observations will be analyzed to assess the long term stability of the calibration, including whether the currently unused steps may need to be implemented in the future. * As of late 2016, there are no known dead or hot pixels on the LORRI detector, so all hot and dead pixel map calibration files contain all zeroes. From the current flat-field calibration file it can be seen that there are many pixels with relative sensitivities up to six times the mean (unity), those called warm pixels. Those pixels are calibrated in the flat-field step. The first 34 pixels (51 bytes) of each LORRI image contain housekeeping information. These bytes are corrupted by LOSSY compression. Please refer to the DOCUMENT/SOC_INST_ICD.* file for details and implications in raw and calibrated datasets. Data ==== The observations in this data set are stored in data files using standard Flexible Image Transport System (FITS) format. Each FITS file has a corresponding detached PDS label file, named according to a common convention. The FITS files may have image and/or table extensions. See the PDS label plus the DOCUMENT files for a description of these extensions and their contents. This Data section comprises the following sub-topics: - Filename/Product IDs - Instrument description - Other sources of information useful in interpreting these Data - Visit Description, Visit Number, and Target in the Data Labels Filename/Product IDs -------------------- The filenames and product IDs of observations adhere to a common convention e.g. LOR_0123456789_0X630_ENG.FIT ^^^ ^^^^^^^^^^ ^^^^^ ^^^\__/ | | | | ^^ | | | | | | | | | +--File type (includes dot) | | | | - .FIT for FITS file | | | | - .LBL for PDS label | | | | - not part of product ID | | | | | | | +--ENG for CODMAC Level 2 data | | | SCI for CODMAC Level 3 data | | | | | +--Application ID (ApID) of the telemetry data | | packet from which the data come | | N.B.

The MET is the time that the data are transferred from the instrument to spacecraft memory and is therefore not a reliable indicator of the actual observation time. The PDS label and the index tables are better sources to use for the actual timing of any observation. The specific keywords and index table column names for which to look are * START_TIME * STOP_TIME * SPACECRAFT_CLOCK_START_COUNT * SPACECRAFT_CLOCK_STOP_COUNT Instrument Instrument designators ApIDs ** =========== ================================== ============= LORRI LOR 0X630 - 0X63B * * Not all values in this range are in this data set ** ApIDs are case insensitive There are other ApIDs that contain housekeeping values and other values.

CATALOG LORRI.CAT DOCUMENTS LORRI_SSR.* SOC_INST_ICD.* NH_LORRI_V###_TI.TXT (### is a version number) Other sources of information useful in interpreting these Data -------------------------------------------------------------- Refer to the following files for more information about these data NH Trajectory tables: /DOCUMENT/NH_MISSION_TRAJECTORY.* - Heliocentric LORRI Field Of View definitions: /DOCUMENT/NH_FOV.* /DOCUMENT/NH_LORRI_V###_TI.TXT Visit Description, Visit Number, and Target in the Data Labels --------------------------------------------------------------- The observation sequences were defined in Science Activity Planning (SAP) documents, and grouped by Visit Description and Visit Number. The SAPs are spreadsheets with one Visit Description & Number per row. A nominal target is also included on each row and included in the data labels, but does not always match with the TARGET_NAME field's value in the data labels. In some cases, the target was designated as RA,DEC pointing values in the form ``RADEC=123.45,-12.34'' indicating Right Ascension and Declination, in degrees, of the target from the spacecraft in the Earth Equatorial J2000 inertial reference frame. This indicates either that the target was either a star, or that the target's ephemeris was not loaded into the spacecraft's attitude and control system which in turn meant the spacecraft could not be pointed at the target by a body identifier and an inertial pointing value had to be specified as Right Ascension and Declination values. PDS-SBN practices do not allow putting a value like RADEC=... in the PDS TARGET_NAME keyword's value. In those cases the PDS TARGET_NAME value is set to CALIBRATION. TARGET_NAME may be N/A (Not Available or Not Applicable) for a few observations in this data set; typically that means the observation is a functional test so N/A is an appropriate entry for those targets, but the PDS user should also check the NEWHORIZONS:OBSERVATION_DESC and NEWHORIZONS:SEQUENCE_ID keywords in the PDS label, plus the provided sequence list (see Ancillary Data below) to assess the possibility that there was an intended target. These two keywords are especially useful for STAR targets as often stars are used as part of instrument calibrations, and are included as part of the sequencing description which is captured in these keywords. Ancillary Data ============== The geometry items included in the data labels were computed using the SPICE kernels archived in the New Horizons SPICE data set, NH-X-SPICE-6-PLUTO-V1.0. Every observation provided in this data set was taken as a part of a particular sequence. A list of these sequences has been provided in file DOCUMENT/SEQ_LORRI_PLUTO.TAB. In addition, the sequence identifier (ID) and description are included in the PDS label for every observation. N.B. While every observation has an associated sequence, every sequence may not have associated observations. Some sequences may have failed to execute due to spacecraft events (e.g. safing). No attempt has been made during the preparation of this data set to identify such empty sequences, so it is up to the user to compare the times of the sequences to the times of the available observations from INDEX/INDEX.TAB to identify such sequences. Time ==== There are several time systems, or units, in use in this dataset: New Horizons spacecraft MET (Mission Event Time or Mission Elapsed Time), UTC (Coordinated Universal Time), and TDB Barycentric Dynamical Time. This section will give a summary description of the relationship between these time systems. For a complete explanation of these time systems the reader is referred to the documentation distributed with the Navigation and Ancillary Information Facility (NAIF) SPICE toolkit from the PDS NAIF node, (see http://naif.jpl.nasa.gov/). The most common time unit associated with the data is the spacecraft MET. MET is a 32-bit counter on the New Horizons spacecraft that runs at a rate of about one increment per second starting from a value of zero at 19.January, 2006 18:08:02 UTC or JD2453755.256337 TDB. The leapsecond adjustment (DELTA_ET = ET - UTC) was 65.184s at NH launch, and the first three additional leapseconds occurred in at the ends of December, 2009, June, 2012 and June, 2015. Refer to the NH SPICE data set, NH-J/P/SS-SPICE-6-V1.0, and the SPICE toolkit documentation, for more details about leapseconds. The data labels for any given product in this dataset usually contain at least one pair of common UTC and MET representations of the time at the middle of the observation. Other portions of the products, for example tables of data taken over periods of up to a day or more, will only have the MET time associated with a given row of the table. For the data user's use in interpreting these times, a reasonable approximation (+/- 1s) of the conversion between Julian Day (TDB) and MET is as follows: JD TDB = 2453755.256337 + ( MET / 86399.9998693 ) For more accurate calculations the reader is referred to the NAIF/SPICE documentation as mentioned above. Reference Frame =============== Geometric Parameter Reference Frame ----------------------------------- Earth Mean Equator and Vernal Equinox of J2000 (EMEJ2000) is the inertial reference frame used to specify observational geometry items provided in the data labels. Geometric parameters are based on best available SPICE data at time of data creation. Epoch of Geometric Parameters ----------------------------- All geometric parameters provided in the data labels were computed at the epoch midway between the START_TIME and STOP_TIME label fields. Software ======== The observations in this data set are in standard FITS format with PDS labels, and can be viewed by a number of PDS-provided and commercial programs. For this reason no special software is provided with this data set. Contact Information =================== For any questions regarding the data format of the archive, contact New Horizons LORRI Principal Investigator: Hal Weaver, Johns Hopkins Univ., Applied Physics Lab Harold A Weaver Johns Hopkins University Applied Physics Laboratory Space Exploration Sector 11100 Johns Hopkins Road Laurel, MD 20723-6099 USA " CONFIDENCE_LEVEL_NOTE = " Confidence Level Overview ========================= During the processing of the data in preparation for delivery with this volume, the packet data associated with each observation were used only if they passed a rigorous verification process including standard checksums. In addition, raw (Level 2) observation data for which adequate contemporary housekeeping and other ancillary data are not available may not be reduced to calibrated (Level 3) data. This issue is raised here to explain why some data products in the raw data set, NH-P-LORRI-2-PLUTO-V3.0, may not have corresponding data products in the calibrated data set, NH-P-LORRI-3-PLUTO-V3.0. Data coverage and quality ========================= Every observation provided in this data set was taken as a part of a particular sequence. A list of these sequences has been provided in file DOCUMENT/SEQ_LORRI_PLUTO.TAB. N.B. Some sequences provided may have zero corresponding observations. Refer to the Confidence Level Overview section above for a summary of steps taken to assure data quality. The LORRI instrument replaces the first 34 12-bit pixels of each LORRI image (408 bits; 51 bytes) with encoded binary header information, so those first 34 pixel values in the first row are not representative of the brightness of the imaged scene at those locations; these pixels are in the bottom-left corner of images displayed left-to-right and bottom-to-top. Furthermore, if the image was LOSSY-compressed before downlink (ApIDs 0x632, 0x635, 0x638, 0x63B *), the header information corrupts the first 40 pixels of the first 8 rows of the image because of the Discrete Cosine Transform compression algorithm. The SOC pipeline extracts these data into the FIRST34 extension of LORRI FITS files, which is also corrupt in LOSSY-compressed files. The SOC calibration pipeline also flags these pixels as bad in the QUALITY_MAP extension of calibrated FITS files; no such flags are available in the raw FITS files; the SOC pipeline did not flag the additional corrupt pixels beyond the first 34 in LOSSY-compressed data until the Pluto P2 delivery late in 2016. * See ApID definitions under the Data section of the Data Set Description, DATA_SET_DESC, in this data set catalog. Observation descriptions in this data set catalog ================================================= Some users will expect to find descriptions of the observations in this data set here, in this Confidence Level Note. This data set follows the more common convention of placing those descriptions under the Data Set Description (above, if the user is reading this in the DATASET.CAT file) of this data set catalog. Caveat about TARGET_NAME in PDS labels and observational intent =============================================================== The downlink team on New Horizons has created an automated system to take various uplink products, decode things like Chebyshev polynomials in command sequences representing celestial body ephemerides for use on the spacecraft to control pointing, and infer from those data what the most likely intended target was at any time during the mission. This works well during flyby encounters and less so during cruise phases and hibernation. The user of these PDS data needs to be cautious when using the TARGET_NAME and other target-related parameters stored in this data set. This is less an issue for the plasma and particle instruments, more so for pointing instruments. To this end, the heliocentric ephemeris of the spacecraft, the spacecraft-relative ephemeris of the inferred target, and the inertial attitude of the instrument reference frame are provided with all data, in the J2000 inertial reference frame, so the user can check where that target is in the Field Of View (FOV) of the instrument. Finally, note that, within the FITS headers of the data products, the sequence tables, and other NH Project-internal documents used in this data set and/or inserted into the data set catalog, informal names are often used for targets instead of the canonical names required for the TARGET_NAME keyword. For example, during the Pluto mission phase, instead of the TARGET_NAME '15810 ARAWN (1994 JR1)' there might be found any of the following: 1994JR1; 1994 JR1; JR1. For all values where the PDS keyword TARGET_NAME is used (e.g. in PDS labels and in index tables), the canonical, PDS-approved names are used (if not, please bring this to the attention of PDS so it can be rectified). However, within the context of this data set, these project abbreviations are not ambiguous (e.g. there is only one NH target with 'JR1' in its name), so there has been, and will be, no attempt to expand such abbreviations where they occur outside formal PDS keyword values. Review ====== This dataset was peer reviewed and certified for scientific use on June 19, 2017. " ABSTRACT_DESC = " This data set contains Calibrated data taken by the New Horizons Long Range Reconnaissance Imager instrument during the Pluto encounter mission phase. This is VERSION 3.0 of this data set. This data set contains LORRI observations taken during the the Approach (Jan-Jul, 2015), Encounter, Departure, and Transition mission sub-phases, including flyby observations taken on 14 July, 2015, and departure and calibration data through late October, 2016. Departure observations include a ring search of the Pluto system and 1994 JR1 observations. This data set completes the Pluto mission phase deliveries for LORRI. This is version 3.0 of this dataset. Changes since version 2.0 include the addition of data downlinked between the end of January, 2016 and the end of October, 2016, completing the delivery of all data covering the Pluto Encounter and subsequent Calibration Campaign. It includes multi- map observations from the Approach phase, observations of the moons, hi- res, full-frame observations from Pluto Encounter and Departure, sliver maps, and ring search observations. There may be some overlap between prior datasets and this dataset, due to only partial, windowed, or lossy data in prior datasets. Observations at closest approach to Pluto are marked with _CA in the Request ID. This dataset also includes functional tests from the Calibration Campaign, including a regular observation of NGC3532. Finally it includes the first set of distant KBO observations. Also, updates were made to the calibration files, documentation, and catalog files. There were minor changes to the level 2 LORRI calibration process, as well as to the LORRI calibration constants for the final Pluto P3 PDS delivery. The process change involves gap removal during calibration. Files with gaps come in many flavors, depending on where the gap lies within the image. This update recognizes some additional possiblities, mainly that the gap might be close to the bottom or top of the image (and therefore the previous algorithm would fail because it filled the gap with median pixel info from both above and below the gap). The new algorithm will take the info from one side of the gap exclusively, when appropriate.
