This is an ICL procedure which creates spectra for all the sources in a ROSAT XRT field found by PSS. To run this procedure, you need to be in the directory containing the raw data, and have a source list available. To invoke it type,
This will produce a number of spectral files called SPEC1 - SPECn where n is the number of the source found by PSS.XRTMSPEC [srclist] [encpsf] [emean]
The procedure adjusts the size of the box used to extract events to account for the variation of the size of the psf across the field.
