We present RCSED, the value-added Reference Catalog of Spectral EnergyDistributions of galaxies, which contains homogenized spectrophotometric datafor 800,299 low and intermediate redshift galaxies (0.007<z<0.6) selected fromthe Sloan Digital Sky Survey spectroscopic sample. Accessible from the VirtualObservatory (VO) and complemented with detailed information on galaxyproperties obtained with the state-of-the-art data analysis, RCSED enablesdirect studies of galaxy formation and evolution during the last 5Gyr. Weprovide tabulated color transformations for galaxies of different morphologiesand luminosities and analytic expressions for the red sequence shape indifferent colors. RCSED comprises integrated k-corrected photometry in up-to 11ultraviolet, optical, and near-infrared bands published by the GALEX, SDSS, andUKIDSS wide-field imaging surveys; results of the stellar population fitting ofSDSS spectra including best-fitting templates, velocity dispersions,parameterized star formation histories, and stellar metallicities computed forinstantaneous starburst and exponentially declining star formation models;parametric and non-parametric emission line fluxes and profiles; and gas phasemetallicities. We link RCSED to the Galaxy Zoo morphological classification andgalaxy bulge+disk decomposition results by Simard et al. We construct thecolor-magnitude, Faber-Jackson, mass-metallicity relations, compare them withthe literature and discuss systematic errors of galaxy properties presented inour catalog. RCSED is accessible from the project web-site and via VO simplespectrum access and table access services using VO compliant applications. Wedescribe several SQL query examples against the database. Finally, we brieflydiscuss existing and future scientific applications of RCSED and prospectivesfor the catalog extension to higher redshifts and different wavelengths.
