FastSpecFit Spectral Synthesis and Emission-Line Catalog

Overview

FastSpecFit is a stellar continuum and emission-line modeling code for DESI which is optimized for speed and simplicity; it uses physically motivated stellar population synthesis and emission-line templates to jointly model the three-camera optical spectrophotometry from DESI and the ultraviolet through infrared broadband photometry.

For a complete description of FastSpecFit please refer to the documentation.
