Release 20141107 Summary of changes: Clock: The clock file keeps the NuSTAR relative time (after barycentric corrections) accurate to ~2 ms and accounts for drifts in the NuSTAR clock caused by temperature variations, etc. New clock files will be produced as the mission continues on a ~monthly basis. added file http://www.srl.caltech.edu/NuSTAR_Public/NuSTAROperationSite/Clockfile/nuCclock20100101v042.fits This version of the clock file contains all clock corrections during the mission up to 2014-11-07 (v42 of the clock correction file) and is required when using barycorr to correct the arrival times of the individual photons. This file can be used for all observations prior to 2014-11-07.
