    Release date Version Description
    2020-08-13 20200813 This CALDB update contains required files for the NuSTARDAS v2.0.0 update which implements a new temperature-dependence during the ARF generation.

    v108 (and later) Clock correction files contain an improvement of the clock offset model that corrects for a ~5ms systematic shift in absolute alignment to UTC time. Corrects for time intervals with no temperature measurements.
