This directory contains the Radio Science Original Data Records (ODR's) for the middle of occultation season 11 (passes 3401-3469) containing passes 3451-3457 which covers the time period between 1987-10-30 and 1987-11-05. The data files are organized as single occultation events which are byte-for-byte dumps of the ODR tapes provided by the DSN. The naming convention for each file follows the tape labeling convention PKCxxxx.ODR where the "xxxx" is the tape number within the sequence. Every data file has an associated PDS label file which describes the data file. The format of the data files is described in the file ODR_FMT.TXT which is an ascii text version of the NASA document 820-13; Rev A, RSC 11-10 "DSN System Requirements Detailed Interface Design 04/88" Also available in the DOCUMENT directory off the root of this disk is a TIFF version of the original document (1 TIFF file per document page). The DOCINFO.TXT file explains the various methods of viewing the TIFF files. In addition to the data and label files there is an index file which contains information from the exterior tape label. The fields in this file include the following: file name DSPR drive number year S/C Number (SC#) Pass Number DSS Number (DSS) Start Time Stop Time comments ****NOTE: PKC0076.ODR is missing record number four (4).*****
