Abstract

Resuits of tests of the SOGS/RSDP software that converts raw FOS data
(photon counts) to countrates (photons/second) are presented. These
are tests of portions of the software that can be run using the
command CALFOS. All of the tests reported here were performed with
synthetic data (i.e. data. produced by special software as opposed to
data produced by the FOS followed by initial processing to reformat
the data and header parameters.) These tests indicate that the RSDP
software correctly calculates a countrate array and an associated
error array (when the number of photons detected is greater than zero)
and properly uses the observational parameters for the data format
that will probably be used most often. Some details of the testing
process are given as weil as information that will allow these tests
to be repeated to check future releases of the software.
