      Generate ACIS exposure maps for celldetect recursive blocking
     
acis_expmap evt2.fits asol.list 
      
        This script generates exposure maps for use with celldetect in
	recursive blocking mode.   It creates a stack, expmap.lis, of
	expmap_bl1.fits, expmap_bl2.fits, expmap_bl4.fits - the 3
	blocking factors used by celldetect for centered ACIS-I
	images.  
       
        acis_expmap expects two arguments: an event file and a list of
	aspect solution files (e.g. "pcad_asol1.lis").  The script
	requires that a stack list be used as input, even if there is
	only one aspect solution file; see "ahelp stack" for more
	information. 
       
        The script produces exposure maps for a single energy of 1.5
	keV.  Users may edit the script to use a different energy
	value.
               
        This script is used in the Running celldetect thread.
