******************************************************************************** NUSTAR ******************************************************************************** - Updates for NuSTARDAS 1.6.0: Please note that this version requires NuSTAR CALDB dated 2016 03/15 or newer and will not work with older versions of the CALDB. Major changes introduced in this version: nusplitsc (NEW TASK): When the primary star tracker (also known as a camera head unit, or CHU) is blinded by the Earth limb or glint from the Sun the data is recorded in 'Mode 06' by the pipeline. In this mode the pipeline uses the spacecraft start rackers (CHUs 1, 2, and 3) to determine the sky position of each count. This sky position can be subtly different when different combinations of star trackers are guiding the observatory pointing, resulting in blurring of the output image. nusplitsc allows the user to generate separate independent output files for each CHU combination, each of which should have reduced blurring and higher fidelity. We note that the absolute position of these images may still be different than the Mode 01 data set and do not recommend using RA/DEC coordinates when extracting produces in these modes without first inspecting the images. See the Observatory Guide as well as Walton et al. (2016) and Grefenstette et al. (2016) for more details. - nucalcsaa: The SOC has optimized new algorithms to automatically generate GTIs that exclude regions of the orbit that produce enhanced background counts in the detector. See the Observatory Guide for a full description of these new modes and their effects. - nupipeline: New options to accomodate the nusplitsc and nucalcsaa tasks. Added optional call to the new 'nusplitsc' module (parameter 'runsplitsc', set to 'no' by default) and modified the call to 'nucalcsaa' from nupipeline. - nuflagbad: Minor bug fix to exclude hot pixels in the output badpixel file (nu*_bp.fits) in case of reprocessed files; - nuscreen: Addition of a new keyword (OBSMODE) storing the NuSTAR observing mode to the output cleaned event files; - nufilter: Addition of the keywords MJDREFI and MJDREFF in the output filter (nu*.mkf) file; - nucoord: Value update of the RA_NOM and DEC_NOM keywords in the +0 and +6 extension of unfiltered event files.
