Synopsis:

Adds together livetime cubes produced by gtltcube.

This tool sums up the livetime contributions from each input file and merges the GTI extensions. It checks to ensure that the tables of HealPix data have compatible shapes for summing together the data. This is the only consistency check that is made between files. The input livetime cube files can be generated by gtltcube, or obtained from the SLAC Data Portal.

Usage: gtltsum infile1 infile2 outfile

General Parameters

  infile1 [file]
    Name of the first livetime cube file or an ASCII file containing a list of livetime cube files, prepended with an "@" sign. The livetime cube file can be generated by gtltcube, or be obtained from the SLAC Data Portal.
     
  infile2 = none [file]
    Name of the second livetime cube file. It will be prompted for only if the first file is also a livetime cube file (i.e., not a list of files). (default: none)
     
  (table = EXPOSURE) [string]
    Name of the extension containing the livetime. This is a hidden parameter.
(default: EXPOSURE)
     
  (table2 = WEIGHTED_EXPOSURE)
    Name of extension containing livetime. This is a hidden parameter.
(default: WEIGHTED_EXPOSURE)
     
  outfile [file]
    Output FITS file name.
     
  (chatter = 2)
    This parameter fixes the output verbosity: no screen output (0), nominal screen output (2), maximum verbosity (4). (default: 2)
     
 
(clobber = yes)
    If true, an existing file of the same name will be overwritten.
     
  (debug = no)
   

Activate debugging mode. (default: no)

When debug is "no", all exceptions that are not caught and handled by individual tool-specific code are caught by a top-level exception handler that
displays information about the exception and then exits. When debug is "yes", such exceptions are not caught by the top-level code. Instead the tool produces a segmentation violation, which is more useful for debugging. When debugging mode is enabled, the tool produces more verbose output describing any errors or exceptions that are encountered.

     
  (gui = no)
    If the parameter specified is "yes", the Graphical User Interface (GUI) mode is activated. This is a hidden parameter. (default: no)
     
  (mode = ql)
    Mode of automatic parameters. This is a hidden parameter. (default: ql)
