Bugs

  1. Degap filename length (16 May 2007)

    There is a 127 character limit to the filename length (including path) of the HRC degap file. If the filename is > 127 characters, then random memory can get over-written.

  2. Incorrect PI range in output file subspace (01 Jun 2010)

    The tool copies the PI range from the input file instead of recalculating it. This results in an incorrect subspace value because the SUMAMPS scale (used since CIAO 4.2) extends from 0-1023, while the previously-used PHA scale extends only from 0-255.

    Here the mismatch is seen in the column range and the subspace:

    unix% dmlist hrc_repro.fits cols | grep "pi "
      17   pi                   chan         Int2           0:1023               Pulse Invariant
    
    unix% dmlist hrc_repro.fits subspace | grep "pi "
      17 pi                   Int2                0:255
