SPEX 2.00 is an X-ray and UV spectral fitting package, written by J. S. Kaastra at the Space Research Organisation of the Netherlands (SRON), which has been designed with the high-resolution X-ray spectra from XMM-Newton and Chandra in mind. The latest public build of SPEX 2.00 is available from the official SPEX website. This site is an unofficial quick start guide to SPEX 2.00.
This website contains the following information:
1) Instructions for converting XMM-RGS spectral files and response matrices to the SPEX format.
2) A walkthrough of the basic SPEX commands
3) A complete list of all the commands
4) More detailed descriptions of cetain commands, provided by Jelle Kaastra
5) A list of the available spectral models
6) Some example SPEX sessions geared towards AGN people
7) A SPEX walkthrough for analysing stellar spectra
8) A list of updates to the version of SPEX used at MSSL
9) The official SPEX manual in Postscript or PDF format.
