NuSTAR CALDB Update (24 Apr 2017)
The NuSTAR CALibration DataBase was updated on April 24, 2017 (CALDB version 20170419). This updates the NuSTAR clock correction file to version 70, valid through 2017-04-19.
HEASOFT 6.21 fixes CALDB Remote Access problems (05 Apr 2017)
The HEASARC now uses secure (https) connections on all its servers, and unfortunately this breaks virtual file access in CFITSIO. This means that remote access to the HEASARC CALDB is also broken using https or http (which is re-directed to https). Remote access users should download HEASOFT 6.21 and set the $CALDB environment variable to ftp://heasarc.gsfc.nasa.gov/caldb. Note that CFITSIO ftp access to the HEASARC servers was broken in versions of HEASOFT prior to HEASOFT 6.21.
