ODR_OCCLOG

Start Time:	1998-01-24T19:15:36	Stop Time:	2001-11-15T18:09:45
This file contains summary information for MGS radio occultation opportunities between January 1998 and November 2001 when the primary data type was the Original Data Record (ODR) produced by the DSCC Spectrum Processor (DSP); this table has 16 columns. Columns include start/stop times for data acquisition, antenna number, data acquisition mode flags, sample rate, bandwidth, bit resolution, record length, number of records, maximum signal-to-noise ratio, ODR or RSR file name, SOE file name, and comments. Columnar data and delimiters require 176 bytes; these are followed by an ASCII carriage-return and line-feed, making the total line length equal to 178 bytes. Orbit numbers in the keywords immediately below (START_ORBIT_NUMBER and STOP_ORBIT_NUMBER) as well as in the COMMENTS column of the tables themselves reflect the MGS Project decision to reinitialize orbit numbers to 1 at the beginning of the MGS Mapping Phase. In addition, the numbers listed here may be slightly different from the numbers kept by the MGS Project office; there were operational advantages for the Radio Science Team to pair ingress and egress occultations and this sometimes led to a discrepancy depending on when the Project-defined orbit number changed relative to the occultations. The difference between official MGS orbit numbers and the orbit numbers shown here should never be more than 1. This file was produced by the Mars Global Surveyor Radio Science Team, under the direction of G. Leonard Tyler.

RSR_OCCLOG

Start Time:	2001-12-13T02:20:00	Stop Time:	2006-11-06T15:12:00
This file contains summary information for each MGS radio occultation opportunity starting in December 2001. Data are organized as a PDS TABLE object with 17 columns of fixed widths. Columns include start/stop times for data acquisition, antenna number, sample rate, filter width, DSP mode, bit resolution, record length, number of records, number of missing records, maximum signal-to-noise ratio, RSR file name, SOE file name, and comments. Columnar data and delimiters require 176 bytes; these are followed by an ASCII carriage-return and line feed, making the total line length equal to 178 bytes. Orbit numbers in the keywords immediately below (START_ORBIT_NUMBER and STOP_ORBIT_NUMBER) as well as in the COMMENTS column of the table itself reflect the MGS Project decision to reinitialize orbit numbers to 1 at the beginning of the MGS Mapping Phase. The numbers listed here may be slightly different from the numbers kept by the MGS Project office; there were operational advantages for the Radio Science Team to pair ingress and egress occultations and this sometimes led to a discrepancy depending on when the Project-defined orbit number changed relative to the occultations. This file was produced by the Mars Global Surveyor Radio Science Team, under the direction of G. Leonard Tyler.
