The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.

HEAsoft v6.3.2 Bug List

Last modified Monday, 21-Apr-2025 17:48:36 EDT

If you are using HEASOFT v6.2 and don't want to upgrade to v6.3.2 just yet, see the HEASOFT 6.3 Bug List.

Please visit the HEASOFT Supported Platforms page for current information about supported operating systems and compilers.

Several packages track bugs separately from this page:

The following is a list of known bugs in v6.3.2 of HEAsoft not covered by the above pages.

  • Source builds on Mac OS X 10.3.x / Darwin 7.x (PANTHER):

    Panther users may hit a build error in the newmakefilter task, stating: 
    ComplexData.hh:153: error: `isnan' undeclared (first use this function)
    To fix this problem, edit the file

    headas-6.3.x/attitude/tasks/newmakefilter/ComplexData.hh

    and remove lines 9 and 13, i.e. uncomment the #ifdef __APPLE_CC__ section: 
    09: /*
10: #ifdef __APPLE_CC__
11: static long isnan(double value) { return __isnand(value); }
12: #endif
13: */
    This code is only necessary on Panther (and breaks builds with newer versions of the Xcode compilers). After making this edit, the build should hopefully go smoothly.

  • rbnrmf:

    The RMF-rebinning task rbnrmf has been updated to fix bugs in the energy binning method: the result for energy-binning should be averages, not sums, and there was an off-by-one error for zero-based channels.
