Welcome to the Documentation for FastSpecFit

Overview

FastSpecFit is a stellar continuum and emission-line modeling code which is optimized for speed and simplicity; it uses physically motivated stellar population synthesis and emission-line templates to jointly model UV/optical spectrophotometry and ultraviolet through infrared broadband photometry (fastspec). Alternatively, it can be used to model just the broadband photometry (fastphot).

FastSpecFit currently only supports DESI spectrophotometric data, although contributions to develop the software for other instruments and surveys are more than welcome.
