This directory contains the Radio Science Original Data Records (ODR's) for
occultation seasons 1 through 4 containing passes 275, 277-290, 337, 340,
352-354 orbits 75, 77, 79-90, 138, 141, 153-155 which covers the time period 
1978-02-17 to 1978-05-08. 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 
ODRXXXX.ODR where the "XXXX" is the tape label number. 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 11-9 "DSN System Requirements Detailed
Interface Design"

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
day of year
SC_ID
DSS Number    (DSS)
Orbit Number
Pass Number
Start Time
Stop Time
Reel Number
