PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2012-04-01 NOTE = "Description of the index directory contents. Updated to include cumulative index." END_OBJECT = TEXT END INDEX Directory Contents The index directory contains tabular index files, accompanied by detached PDS labels, intended for use in data management systems. The following files are found in this directory. indxinfo.txt - The file you are reading. index.lbl - Detached PDS label for index.tab. index.tab - Index table for the current Cassini Imaging Science Subsystem Raw EDR volume. cumindex.tab - Index table for this volume and all preceding volumes in this dataset. cumindex.lbl - Detached PDS label for cumindex.lbl. Notes on Using the Image Index The index table in this directory contains one row (record) for each image on this Cassini Imaging Science Subsystem Raw EDR volume. The columns in this table are keywords related to each image. These keywords include all of the detached label keywords such as TARGET_NAME FILTER_NAME START_TIME OBSERVATION_ID etc. Also included are many calculated geometrical keywords such as: TARGET_DISTANCE TARGET_LIST, CENTER_LONGITUDE INCIDENCE_ANGLE PIXEL_SCALE etc. The table is formatted so that it can be read directly into many database systems. All fields are separated by commas, and character fields are enclosed in double quotation marks ("). Character fields are left justified and numeric fields are right justified. Each record ends with ASCII carriage return and line feed characters. This allows the table to be treated as a fixed length record file on computers that support this file type and as a normal text file on other computers. The index.lbl file is a PDS label file that describes the content and structure of the fields in the index table, including field name, format, and description. The values for start byte and number of bytes listed in the label file do not include commas between fields or quotation marks surrounding character fields. Please note that the geometrical keywords are calculated using the project-provided reconstructed SPICE kernels. In some cases, an auto-navigated c-kernel is used in place of the ACS reconstructed c-kernel. Please read the section entitled "ISS Auto-navigation" in the dataset file of the catalog directory for more information on the use and accuracy of this data.
