PUBLICATION_DATE = 2003-10-30 /* Peer Review Date */ END_OBJECT = TEXT END Overview ======== This volume contains 12-, 25-, 60-, and 100-micron photometry of the dust coma of comet 9P/Tempel 1 during its 1983 apparition. The photometry was derived from reconstructed observations acquired by the Focal Plane Array (FPA) instrument on the Infrared Astronomical Satellite (IRAS). The types of observations were Sky Survey Atlas (ISSA) scans and Additional/Pointed Observations (AO). A comprehensive discussion of these data was provided by Carey Lisse and included as documentation. The reconstructed images used for this photometric analysis are available in the PDS data set DI/IRAS-C-FPA-5-9P-IMAGES-V1.0. These data support the analysis of the dust environment of Tempel 1 for the NASA Deep Impact Mission. Volume Format ============= This volume has been formatted according to the ISO-9660 level 2 Interchange Standard. File Format =========== PDS label formats and documentation conform to standards as defined by the Planetary Data System Standards Reference (JPL Document D-7669, Part 2JPL D-7669, Part 2, August 1, 2003, Version 3.6) and the Planetary Science Data Dictionary (JPL D-7116, August 2002, Rev. E). 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 MS-DOS/Windows, Unix, and VMS operating systems.
