The spectral energy distribution (SED) modeling and fitting is the principal technique for the determination of fundamental galaxy parameters, such as its stellar mass and star formation rate (SFR).
However, the accuracy of the derived parameters is sensitive to the models being used and the assumed Bayesian priors.
In a paper published in the Astrophysical Journal, Strategies for Obtaining Robust Spectral Energy Distribution Fitting Parameters for Galaxies at z ~ 1 and z ~ 2 in the Absence of Infrared Data, recent IU graduate student Chandler Osborne has undertaken a systematic investigation of the assumptions relating to the star formation history, stellar metallicity, dust attenuation and the choice of stellar population models. The result of the study is a set of recommendations regarding the SED modeling. In addition, these best practices were applied to galaxies at redshifts between 0.7 and 2.5 from the CANDELS survey, resulting in a catalog of >60,000 galaxies. CANDELS survey has been a workhorse of studies aimed at the "cosmic Noon", a period of rapid growth of galaxies. The catalog is available from the journal website as well as the dedicated webpage, Candels Galaxy Parameters Catalog.
