sbdr2isis - Convert Cassini SBDR table to an ISIS table
This program will convert a PDS-formatted Cassini SBDR
table to an ISIS-formatted binary table. The data that is
transferred to the output ISIS table can be limited by
using the NTHROW, TIME, BURST_ID, BEAM_NO, and RADMOD
parameters.

The NTHROW parameter allows for the user to specify that
only every nth row is to be transferred to the ISIS table.
If NTHROW is set to 1, then every row will be transferred.
If NTHROW is set to 2, then every other row will be
transferred. The TIME parameter allows for a min/max time
range to be specified. The time must be input using the
UTC day of year format yyyy-dddThh:mm:ss.sss. The BURST_ID
parameter allows for a min/max burst id range to be
specified. The BEAM_NO parameter allows for a set of beam
numbers to be specified. The RADMOD parameter allows for a
set of radar modes to be specified. A TAE NULL value in the
TIME, BURST_ID, BEAM_NO, or RADMOD parameters will result in
the complete range of those parameters being transferred to
the output ISIS table.

ADDITIONAL NOTES:

Parm	Description
FROM	This is a PDS-formatted SBDR table created by the Cassini mission.
TO	This is the output ISIS-formatted binary table.
BYTEORDER	This is the byte order of the FROM file. The "Cassini Radar Burst Ordered Data Products SIS" document specifies that these files will all be in LSB format, but this is not always the case. There is not a keyword in the PDS table that specifies the byte order of the table, so this parameter must be used to determine the byte order.
SBDRTBL	This table provides a detailed description of the fields to extract from the input PDS-formatted SBDR table. The first record describes how many rows are in the SBDRTBL and gives the locations of fields relating to the TIME, BURST_ID, BEAM_NO, and RADMOD parameters in this program. Every other record in the file gives the long name, short name, start byte, number of bytes, and format of each field that are to be extracted by this program. This program uses the $ISISDATA/SBDR.TBL by default. Used to reduce the size of the output ISIS table. Every nth row will be recorded in the output table. If NTHROW is set to 1, then every row will be recorded. If NTHROW is set to 2, then every other row will be recorded.
TIME	This parameter can be used to specify a time range that can be used to limit the data that gets ported from the PDS table to the ISIS table. The time must be input using the UTC day of year format: yyyy-dddThh:mm:ss.sss If this parameter is set to the TAE NULL value, then the entire time range of the input PDS file will be transferred to the output ISIS file.
BURST_ID	This parameter can be used to specify a burst id range that can be used to limit the data that gets ported from the PDS table to the ISIS table. If this parameter is set to the TAE NULL value, then the entire burst id range of the input PDS file will be transferred to the output ISIS file.
BEAM_NO	This parameter can be used to specify a set of beam numbers that can be used to limit the data that gets ported from the PDS table to the ISIS table. If this parameter is set to the TAE NULL value, then the entire beam number range of the input PDS file will be transferred to the output ISIS file. The BEAM_NO can be any integral number in the range 1 to 5.
RADMOD	This parameter can be used to specify a set of radar modes that can be used to limit the data that gets ported from the PDS table to the ISIS table. If this parameter is set to the TAE NULL value, then the entire radar mode range of the input PDS file will be transferred to the output ISIS file. The RADMOD can be any integral number in the range 0 to 15. However only the following values are currently in use for the radar_mode field of the SBDR that will be compared to RADMOD: 0=Scatterometry, 1=Altimetry, 2=Low resolution SAR, 3=High resolution SAR, 4=Radiometer only. Adding 8 to any of these values indicates auto-gain is enabled. Auto-gain is N/A for Radiometer only mode.
