RECORD_TYPE = "STREAM" OBJECT = TEXT NOTE = "AAREADME file for Deep Impact Thermal-Vacuum 3 ITS Data Archive" PUBLICATION_DATE = 2004-10-15 /* Peer Review Date */ END_OBJECT = TEXT END Overview ======== This volume contains images acquired by the Imaging Targeting Sensor's Visible CCD (ITS) during the third preflight thermal-vacuum test (TV3) of the Deep Impact instruments. Data on this volume are being used for ground calibration of the ITS instrument. 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 MS-DOS/Windows, Unix, and VMS 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.
