" PUBLICATION_DATE = 2011-06-30 END_OBJECT = TEXT END Introduction ============ This dataset contains raw images of comet 103/P Hartley 2 acquired by the Medium Resolution Visible CCD (MRI) from 05 September through 26 November 2010 during the Hartley 2 encounter phase of the EPOXI mission. Clear-filter and CN images of the comet were acquired throughout this phase; OH, C2, and dust continuum images were only acquired for several days spanning closest approach. Volume Format ============= This single-volume dataset has been formatted according to the ISO-9660 level 2 Interchange Standard for directories and file names as described in Version 3.7 of the PDS Standards Reference. File Formats ============ All text documents and other meta information files such as descriptions, PDS object definitions, and detached PDS labels are stream format files, with a carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of the record. This allows the files to be read by various operating systems. Volume Contents =============== Files on this single-volume dataset are organized into a set of subdirectories below the top-level directory. The following table shows the general structure and content. The top-level of the volume is indicated by a single forward slash (/) and subdirectory names are surrounded by forward slashes (/). See the *INFO.TXT files located in each subdirectory for specific information about the contents the subdirectory. / Top level of this volume (dataset) | |-- AAREADME.TXT This file | |-- VOLDESC.CAT Description of logical contents of this volume | |--/CATALOG/ Directory containing PDS catalog files providing | overviews of the mission, instrument, and dataset | |--/DATA/ Directory containing raw data products | | | +--/YYYY/ Multiple year directories, as needed | | | +--/DDD/ Multiple day-of-year directories | | | |-- *.FIT FITS file, 2-D spectral image with one extension | +-- *.LBL PDS label, one for each FITS file | |--/DOCUMENT/ Directory containing documents most useful for | understanding this dataset | |--/EXTRAS/ Directory containing value-added items | +--/INDEX/ Directory containing PDS index files Whom to Contact for Information =============================== Questions regarding the scientific elements of this dataset should be directed to: Michael A'Hearn Principal Investigator, EPOXI Department of Astronomy, University of Maryland College Park, Maryland 20742 USA Jessica Sunshine Deputy Principal Investigator, DIXI Department of Astronomy, University of Maryland College Park, Maryland 20742 USA Kenneth Klaasen Calibration and Sequencing Lead, EPOXI Jet Propulsion Laboratory 4800 Oak Grove Drive Pasadena, CA 91109 USA Questions about data formats and geometry-related information should be directed to: Brian Carcich and Steve Sackett EPOXI Science Data Center Department of Astronomy, Cornell University 610 Space Sciences Building Ithaca, NY 14853 USA Questions regarding the PDS elements in this dataset should be directed to: Stephanie McLaughlin EPOXI Archive Team Department of Astronomy, University of Maryland College Park, Maryland 20742 USA
