# MODULE acs_cor_sched_check
#
#******************************************************************************
"""This tool performs a calendar check that the appropriately tagged ACS
Coronagraphy SUs contained within Timing Linksets contain no other ACS
SUs scheduled withing the gaps of the ACS/COR linkset.

TITLE: acs_cor_sched_check.py
DEVELOPER: Merle Reinhart, 31-Jan-2003

PURPOSE: Verify the correct lack of ACS SUs between ACS Coronagraphy
SUs within the same Timing Linkset.

USAGE: do acs_cor_sched_check

where is the name of the saved calendar that you
wish to check. NOTE: this tool will
overwrite the current map files when run
in standalone mode.

RETURNS: Nothing when run in standalone mode.
pf_status when run as part of the calendar checklist.

MOD HISTORY:
9/28/09 drc modified for candlist -disp output issue with spss build 49.9
