ASTPOL

This process is a file poller process that serves as the interface between the OMS Pipeline and the Astrometry Pipeline. Its purpose is to poll the OMS_ASTDATA_DIR to find corresponding pairs of astrometry .AKX and .ARX files that have been generated by the OMS Pipeline OMSANL process. The .AKX and .ARX files contain astrometry header keywords and raw telemetry data respectively.

When a .AKX/.ARX file pair is found, the ASTPOL process will do the following:

create an OSF for the file pair
create an observation trailer file
append an "_proc" to the names of the .AKX and .ARX files
set the OSF to trigger the SS_AST process

ASTPOL Process Modes

Pipeline Mode

       ASTPOL -p opus_definitions_dir:your.path  (in task line of resource file)

              where: ASTPOL = command name
                         -p = denotes path file specification follows
                     opus_definitions_dir:your.path = path file to use

ASTPOL Process I/O

       INPUT:
          OMS_ASTDATA_DIR: F*M.akx - Astrometry Header Keywords Files
                           F*M.arx - Astrometry Telemetry Data Files  

       OUTPUT:
          OMS_ASTDATA_DIR: F*M.akx_proc - Astrometry Header Keywords Files
                           F*M.arx_proc - Astrometry Telemetry Data Files
