The LASCO standard processing routines are:

   unpack_all_science	Unpack raw quicklook TM frames from DACS or ECS
   unpack_lz_science	Unpack raw level-0 TM frames
   write_closed		Writes the filename of the last image generted by
			  DACS or the unpack routines

   reduce_main		IDL procedure to replace reduce.cron
   
   reduce_image		Top level routine to perform image reduction tasks
			Controls processing flow
			Makes entries into dbms
   reduce_transfer	Transfer and rename new .img or .mem file into 
                          appropriate subdirectory in tree
			Indicates if level 0.5 processing necessary
			Makes entries into dbms
   reduce_level_05	Perform all level 0.5 processing
