- Locate the installation directory of your xselect by 'which xselect' after initialize your HEASOFT environment.
- Add the lines in ''xselect_wxt.mdb' at the end of the 'xselect.mdb' found in your xselect directory.
- Extract products (image, light curve, spectrum) as the usual way in xselect.
- The region used for the source spectra must be a circle with the radius of 67 physical pixel; thus the spectrum will be compatible with the distributed response files.
