CDS INSTRUMENT: Found that 6 deferred commands were not loaded to the
 instrument when the plan was loaded on April 18.  One of the deferred
 commands was to run 3 other studies.  2 of the studies were lost, and
 the third was able to be run.  The cause is under investigation.  Also,
 rebooted the secondary due to an SEU.
