  • XSPEC 12.9.0p Released (28 Jul 2016)
    Patch 12.9.0p, released July 28, Allows unlinking of an already linked parameter in a Python-coded local model in PyXspec.
  • The South Atlantic Anomaly (SAA) and NuSTAR Data (28 Jul 2016)
    The NuSTAR spacecraft flies through regions of the Earth's radiation belts, e.g., the SAA, in parts of its orbit, resulting in an enhanced background in its detectors. The NuSTAR team has some advice about how to analyze data affected by such high backgrounds (which is particularly applicable for fainter X-ray sources) here.
  • Correction to NuSTAR CALDB Update 20160706 (28 Jul 2016)
    There was an error in the NuSTAR CALDB update version 20160706 in which the caldb.indx file was pointing to an older CALDB version (20151008). This has now been fixed, and the tar files have been updated. If you have previously downloaded NuSTAR CALDB 20160706, you should re-download and re-install this version, or use Remote Access to access version 20160706 of the NuSTAR CALDB.
  • NuSTAR CALDB Update (22 July 2016)
    The NuSTAR CALibration DataBase was updated on July 22, 2016 (CALDB version 20160706). This updates the NuSTAR clock correction file to version 59, valid through 2016-07-06.
  • NuSTAR CALDB Update (21 Jul 2016)
    The NuSTAR CALibration DataBase was updated on July 21, 2016 (CALDB version 20160606, corresponding to the internal NuSTAR project release 20160606).
