I've not really looked at the page yet; but already I know that I need HELP! WebSpec is a WWW interface for the X-ray spectral fitting package, XSPEC. It simulates spectral data for a variety of X-ray missions/instruments. WebSpec can not be used to analyze real data. Latest News : 12/16/09 Updated for Chandra Cycle 12.
