About the UPenn SDSS PhotDec Catalog

This catalog contains fits of galaxies drawn from the SDSS catalog. The catalog contains ~680,000 galaxies from the SDSS DR7 spectroscopic sample. 2D decompositions in the g, r, and i bands for each of the DeVacouleur's, Sersic, DeV + exponetial disk and Sersic + exponential disk models are provided. The catalog is cross-matched to many other catalogs for analysis (Yang Halos, MaxBCG, JHU Stellar Masses, UKIDSS, GALEX, and more).

Papers describing the methodology and the data:

• Simulations of single- and two-component galaxy decompositions for spectroscopically selected galaxies from the Sloan Digital Sky Survey
• A catalogue of 2D photometric decompositions in the SDSS-DR7 spectroscopic main galaxy sample: preferred models and systematics
• A catalogue of 2D photometric decompositions in the SDSS-DR7 spectroscopic main galaxy sample: extension to g and i bands

Some of the papers that use the data:

• The massive end of the luminosity and stellar mass functions and clustering from CMASS to SDSS: evidence for and against passive evolution
• The high mass end of the stellar mass function: Dependence on stellar population models and agreement between fits to the light profile
• On the Intermediate-redshift Central Stellar Mass-Halo Mass Relation, and Implications for the Evolution of the Most Massive Galaxies Since z~1
• Systematic effects on the size-luminosity relation: dependence on model fitting and morphology
• No Evidence for a Dependence of the Mass-Size Relation of Early-type Galaxies on Environment in the Local Universe
• The massive end of the luminosity and stellar mass functions: dependence on the fit to the light profile
• Size evolution of spheroids in a hierarchical Universe
