The DOCUMENT directory contains documentation on the archival data
set and files within the data set.
Each file is in ASCII; except where indicated, there are 80 characters
per line in each file. Each line is delimited with a carriage-return (ASCII
13) line-feed (ASCII 10) pair.
The following are present on each volume. They include Software
Interface Specifications describing either the volume or Standard Data
Products in this data set.
DOCINFO.TXT
A brief description of the files within the DOCUMENT directory (this
file).
RSADCSDP.TXT
A Software Interface Specification (SIS) for the archival volume. This
document describes the structure and content of the volume.
RSTP.TXT
The SIS for files containing temperature-pressure profiles derived from
radio occultation measurements. Two versions of the profiles are covered:
standard resolution (data type TPS) and high-resolution (TPH).
OCCSUM.TXT
The SIS for Occultation Summary files. Two versions of the file are
covered: files containing summaries of standard resolution profiles (data
type OCS) and files containing summaries from high-resolution profiles (OCH).
LOSAPDR.TXT
The SIS for Line of Sight Acceleration Profile Data Records (data
type LOS).
SHADR.TXT
The SIS for files containing Spherical Harmonic models (such as gravity
fields or topography) in ASCII formats (data type SHA).
SHBDR.TXT
The SIS for files containing Spherical Harmonic models (such as gravity
fields or topography) in binary formats (data type SHB).
RSDMAP.TXT
The SIS for Radio Science Digital Map products (data type IMG).
The following include Software Interface Specifications which
describe Special Data Products in this data set:
EDS.TXT
The SIS for ionospheric electron density profiles, produced occasionally
as a by-product of the radio occultation investigation. Two versions of the
profiles are covered: standard resolution data (data type EDS) and
high-resolution (EDH).
SRX.TXT
The SIS for files produced during the Surface Reflection investigation.
There are three data types: geometry (SRG), images (SRI), and tabulated
calibrated observables (SRT).
The following are documents included on this volume because of their
association with certain data files which also appear:
OCCLOGM3.TAB
A table of data acquisition parameters for radio occultation and test
opportunities between December 1999 and September 2001. The table gives
dates and times, DSN antenna numbers, signal-to-noise ratio, and file names
of the ODR file for each observation opportunity. There are also terse
indicators of data quality. Detached label OCCLOGM3.LBL describes the
format and content of OCCLOGM3.TAB in detail.
