Photometric redshift catalog from the RCS
Listed in IVOA Registry (Virtual Observatory)
The Red-Sequence Cluster Survey (RCS, Cat. <J/ApJS/157/1>) provides a large and deep photometric catalog of galaxies in the z' and R_c_ bands for 90{deg}^2^ of sky, and supplemental V and B data have been obtained for 33.6{deg}^2^.
Description
We compile a photometric redshift catalog from these four-band data by utilizing the empirical quadratic polynomial photometric redshift fitting technique in combination with CNOC2 and GOODS/HDF-N redshift data.
The training set includes 4924 spectral redshifts. The resulting catalog contains more than one million galaxies with photometric redshifts <1.5 and R_c_<24, giving an rms scatter {sigma}({Delta}z)<0.06 within the redshift range 0.2<z<0.5 and {sigma}({Delta}z)<0.11 for galaxies at 0.0<z<1.5.
