The routines GT_SXS1, GT_SXS2, GT_HXS, GT_GRS1, GT_GRS2, GT_RBMSD, and GT_RBMSC routines will extract the average counts/sec for the selected channel.
The input can be roadmap, index, or observing log and it will
get the proper structure tag and decompress it properly to
return counts/sec/sensor.
It is possible to get a string defining the
channel selected by using the title keyword option.
