DESI Early Data Release (Fuji)


Welcome to the data portal for the DESI FastSpecFit value-added catalogs!

FastSpecFit is a stellar continuum and emission-line modeling code for DESI which forward-models the three-camera optical spectrophotometry jointly with the optical through infrared broadband photometry of galaxy and quasar targets in order to extract a wide range of observed and intrinsic physical properties.

Please refer to the FastSpecFit documentation for full details regarding the code and this data release, particularly the required acknowledgments and conditions of use. Questions, problems, or feature requests can be communicated to the FastSpecFit development team by filing a ticket.

Have fun exploring the data!
