***** FILE INDXINFO.TXT Index File Information This file contains a description of the index tables created for the spacecraft data submitted to the International Halley Watch. For those experiments for which a large number of files were archived, a separate table was created and placed into a subdirectory designated by the experiment code. These include the dust spectra and image experiments, where the former has been subdivided into detection "modes" including a test sequence. When appropriate, the image index tables have been broken into convenient time sequences near encounter. In addition, for the case of the processed TVS images from KFKI, the index tables are further divided according to the process - filtered, sharpened, filtered with aspect correction, sharpened with aspect correction, filtered with aspect and range correction, sharpened with aspect and range correction, and those images used to determine the flatfields. The index tables carry information about the experiment. To locate data use the file CDSTRUCT which identifies the filename (with path), size and starting logical block number (LBN). 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. *.IDX - 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.
