#  Run the sos commands.  This command is called from the sos daemon when new files are
#  written by the icc.  The commands run are:
#
#  Check to make sure the file is a BOSS exposure.  Return if not.  [STEP SKIPPED]
#  Check to make sure the file is no a test expose.  Return if it is.
#  Call IDL aporeduce
#  Check if exposure is a science exposure.  Return if not.
#  Call script to get S/N
#  Call script to update plateDb
