        show_tgain_corr.sl |

        acis_bkgrnd_lookup | 
        
          Updated to version v1.12.
           
            The script has been updated for use with the new ACIS
            blank-sky background files released in CALDB 3.4.0.  The
            script is NOT backward-compatible; you must upgrade to
            CALDB 3.4.0 to use acis_bkgrnd_lookup v1.12.  A list of
            specific changes made is available in the help file
            ("ahelp acis_bkgrnd_lookup").

        | merge_all | 
	
	  Updated to version v3.6.
	   
	  A "[subspace -expno]" filter was added to the dmmerge
	  command.  This is needed as a workaround for a problem
	  merging data with different EXPNO ranges.    If you intend
	  to create lightcurves binned on exposure number, read the
	  caveat in the help file ("ahelp merge_all").
