Status: Archived

This volume contains images acquired during the preflight thermal-vacuum test (TV4) of the High Resolution Imager's Infrared Spectrometer (HRII) and Visible CCD (HRIV) and the Medium Resolution Imager's Visible CCD (MRI) for the Deep Impact Mission. These instruments reside on the Flyby spacecraft. Data from TV4 cover the time period of 23 February 2003 through 12 March 2003. TV4 was conducted at Ball Aerospace.

The data total over 19Gb. The individual day directories are presented here as separate tar files for those with sufficient interest and bandwidth to download them in their entirety.

An overview of the volume contents is provided in the aareadme.txt, a flat text file with an attached label.

Catalog Files

Catalog files contain the overview information and parameters used in loading the PDS central catalog, specifically, or for developing other interfaces to the data outside of PDS. The information they contain, particularly in their descriptive text fields, should be clear, complete, and understandable to a research user who is not necessarily a mission or instrument specialist. The mission, instrument host, and instrument catalog files for this archive are intended to be brief because the project team is pursuing permissions from Space Science Reviews to include recently submitted papers in all Deep Impact archival data sets.

These files are located in the catalog/ subdirectory. The directory contents are described by the catinfo.txt file.

• Mission Catalog File
• Flyby Spacecraft Catalog File
• HRII Instrument Catalog File
• HRIV Instrument Catalog File
• MRI Instrument Catalog File
• Data Set Catalog File
• Ground Calibration Target File
• Tempel 1 Target Target File
• References File
• Personnel Catalog File

Temperatures for various components of the HRII/HRIV instruments as well as the MRI instrument were automatically recorded, approximately every 5 minutes, by two thermister monitors. One monitor recorded 10 of the 13 HRI temperatures; the second monitor recorded the remaining 3 HRI temperatures and all of the MRI temperatures. The resulting temperature data were grouped by HRII/HRIV and MRI and stored in fixed-width, comma-separated, ASCII tables with detached PDS labels.

• templog_tv4_hri.tab is the temperature table for the HRII/HRIV instruments.
• templog_tv4_hri.lbl is the label.
• templog_tv4_mri.tab is the temperature table for the MRI instruments.
• templog_tv4_mri.lbl is the label.

Calibration Files

The calib/ directory contains fixed calibration data for the components of the HRIV and MRI instruments. The directory contents are described by the calinfo.txt file.

• calib/hriv contains one transmission profile table for each of the 9 HRIV filters. The tables, *.tab, are a fixed-width, comma-delimited ASCII tables with detached PDS labels, *.lbl.
• calib/mri contains one transmission profile table for each of the 9 MRI filters. The tables, *.tab, are a fixed-width, comma-delimited ASCII tables with detached PDS labels, *.lbl.

Index Files

The index/ directory contains an index into the data files included on this volume. All index files are fixed-width, comma-delimited ASCII tables.

• indxinfo.txt describes the directory contents.
• index.tab is a a fixed-width, delimited index table. For image data on this volume, table entries contain useful image parameters, such as instrument mode and experiment type.
• index.lbl is the label for the index file.
