UV-to-FIR analysis of sources in the EGS. II.

Based on the ultraviolet to far-infrared photometry already compiled and presented in a companion paper (Barro et al. 2011, Cat.
Description
J/ApJS/193/13), we present a detailed spectral energy distribution (SED) analysis of nearly 80000 IRAC 3.6+4.5um selected galaxies in the Extended Groth Strip. We estimate photometric redshifts, stellar masses, and star formation rates (SFRs) separately for each galaxy in this large sample.
The catalog includes 76936 sources with [3.6]<=23.75 (85% completeness level of the IRAC survey) over 0.48deg^2^. The typical photometric redshift accuracy is {Delta}z/(1+z)=0.034, with a catastrophic outlier fraction of just 2%. We quantify the systematics introduced by the use of different stellar population synthesis libraries and initial mass functions in the calculation of stellar masses.

We find systematic offsets ranging from 0.1 to 0.4dex, with a typical scatter of 0.3dex. We also provide UV- and IR-based SFRs for all sample galaxies, based on several sets of dust emission templates and SFR indicators. We evaluate the systematic differences and goodness of the different SFR estimations using the deep FIDEL 70um data available in the Extended Groth Strip.
Typical random uncertainties of the IR-bases SFRs are a factor of two, with non-negligible systematic effects at z>~1.5 observed when only MIPS 24um data are available.
