RECORD_TYPE = "STREAM" OBJECT = TEXT NOTE = " AAREADME file for the Deep Impact ITS Raw Image Archive of the 9P/Tempel 1 Encounter" PUBLICATION_DATE = 2005-12-31 END_OBJECT = TEXT END Introduction ============ This volume contains raw, comet 9P/Tempel 1 images and science calibration data acquired by the Deep Impact Impactor Targeting Sensor Visible CCD Camera (ITS) during the encounter phase of the mission. These data were collected from May 1 through July 4, 2005. Volume Format ============= This volume has been formatted according to the ISO-9660 level 2 Interchange Standard. 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 volume are organized into a set of subdirectories below the top-level directory. The following table shows the structure and content of these directories. In the table, directory names are enclosed in square brackets ([]). See the *INFO.TXT files in some directories for specific information on the files in that directory.
