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.

faint

ASCA SIS faint to bright conversion


Perform faint-to-bright conversion on all files currently read into XSELECT. If the datamode is set to faint, then the EXTRACT command will run FAINT before extracting the spectra,..., provided of course you have not already done so.

For more details see the faint help page (i.e. from Xselect type $fhelp faint).

If you specify that you want to convert to bright2 mode, then you can either input (dfefile=your_filename), or have xselect create for you, (dfefile=MAKE) a Dark Frame Error file (see the help page for faintdfe for more details), which will be fed to the ftool faint. dfefile=NONE turns this option off.

If you set sispi=yes (the default) faint will fill the PI columns of the resultant BRIGHT or BRIGHT2 mode data files.

Syntax:

xsel >  faint <bright> <split> <dfefile> <echo> <maxgrade>  
              [sis01echo] [sis02echo] [sis03echo] [sis11echo] 
              [sis12echo] [sis13echo] [binsec] [sispi] [zerodef]
