The HEASARC Calibration Database
Caldb manager: Dr. M. F. Corcoran
The HEASARC's calibration database (CALDB) system stores and indexes datasets
associated with the calibration of high energy astronomical instrumentation. The
system can be accessed by users and software alike to determine which
calibration datasets are available, and which should be used for data reduction
and analysis. (Read

Who's who at the CALDB (and who was who)
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.
Hitomi CALDB Data Updated (07 Mar 2017)
The Hitomi CALDB has been updated for the SGD (update version 20170208), and general spacecraft caldb (update version 20170208), and the Hitomi caldb superindex (update version 20170208).
Swift CALDB Data updated (07 Mar 2017)
A new Swift clock correction file has been added to the Swift SC Caldb (CALDB update version 20170306)
NuSTAR CALDB Update (24 Feb 2017)
The NuSTAR CALibration DataBase was updated on February 24, 2017 (CALDB version 20170222). This updates the NuSTAR clock correction file to version 69, valid through 2017-02-22.
