For simplicity and historical reasons it has been preserved. This file contains a description of the index tables created for the SL9 spacecraft data submitted to the Small Bodies Node. For those missions/ experiments for which a large number of files were archived, a separate table was created and placed into this directory designated by the experiment code. The index tables carry information about the scientific parameters for the experiment. To locate any file on the CDROM use CDSTRUCT which identifies the filename (with path), and size. The VOLINDEX file carries information about each data entry and ancillary file. For the SSI data, the index file IMGINDEX.TAB for the submitted data on GO_0016 has been copied to the current volume and edited to reflect only the comet Shoemaker-Levy 9 data. The detached label has the description modified to reflect that the current CD-ROM actually has the same REDR files. The modified label follows current PDS standards. In addition, on GO_0016, the SL9INDEX.TXT file has been converted into an index (SSIINDEX.TAB and *.LBL) with appropriate filenames and path. For NIMS data, a chronological index for the reflectance data was created. Note that the one calibration file is listed at the end of the table as no time was provided. The EDR files do not have an index file as they are separated into individual directories as copied from the original volume, GO_1004. There are two types of files in each subdirectory, distinguished by the extensions on the file names. The filenames themselves identify the experiment which was used to produce each index. The types of files are: *.LBL - These are PDS labels describing the data tables. They already contain pointers to the data tables, so no further steps are required to make them accessible to PDS table-processing software. *.TAB - These files contain the actual metadata records from each file. They are ASCII tables and each line ends with the characters (ASCII 13 and 10 respectively). All fields in the tables are fixed width.
