To find and download HEASARC data in the cloud, you can use astroquery.heasarc or download our new tool, hark.

The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.

Clean GIS data using RTI-PHA window


This task uses the RTI-PHA window contained in the calibration files rti_gis_nnnnn.fits, from the CALDB (or ftools refdata area) to reject background events. You can also enter your own copy of the file with the parameter rti_table_user. The filtered output is placed in the workspace, and will be used in further calls to extract,...

Some ASCA data has the parameter RISEBINS=0. This data has no RISE TIME information, and you cannot run GISCLEAN on it. Xselect will warn you that you have this kind of data.

Also note that MPC mode data has no rise time information. So GISCLEAN is not appropriate for it either.
