CDS INSTRUMENT: 
  Emergency study was not completely deleted from the DCS by cpt/LOADPLAN.
  This occured on the previous day as well causeing the emergency study to
  abort SYNOP and run instead.  
  A parity error occured the in primary processor memory space.  The parity 
  error is in a safe location.

CDS GROUND SYSTEM: 
  Some problems occurred while trying to run CPT over the weekend plan.  It
  appears that due to the multiple pointing utilized for the GARCH studies, 
  that it filled up the sequence tables and kept crashing CPT.  The CPT runs
  were then broken up into 2 runs over 3 days.  CPT then worked.

  during the submode switch.  It did not crash, therefore we will try and
  run through the next submode switch as well this upcoming Friday.

  A NIS Setup Register A Failure System Error occured.  The NIS will be reset
  when convenient.
  A parity error was detected in the secondary (science) processor memory
  space.  The secondary processor was restarted at 21:14 UT.  Note, that due
  to operator error, the OPS were not position correctly for the start of the
  study at 21:25 UT (ATRIC22W), therefore the first part of this study was
  performed with the wrong pointing. 
  The reason for the detector 1 trip on the 26th was found:  the studies
  in mk_plan were overlapped such that one two studies attempted to run
  at once.  Detector 1 tripped.  Detectors 2, 3, and 4 did not run at all.
  The SPECT_1 study that ran 3 hours later reset the detectors and all was
  fine.
