Bugs

  1. Minimum and maximum values for the binspec parameter

    If there is no min/max given in the binspec parameter, the tool returns the min/max for the datatype for the specified column. If this is a large range, it will fail with

    # dmgroup (CIAO 4.2): dsALLOCERR -- ERROR: Could not allocate memory.
    

    Workarounds:

    1. Provide a binning specification in the binspec parameter.

    2. If the column range is missing or too large, one may be forced by filtering the column. For example, to establish a PHA range:

      unix% pset dmgroup infile="acis_evt2.fits[pha=1:4096]"
