Optical photometric parameters for galaxies in the twenty EDisCS cluster fields measured from our deep VLT/FORS2 imaging. Mid-z clusters were observed in BVI and high-z clusters were observed in VRI.
The catalogs contain six types of magnitude (r=1",2",3" aperture magnitudes as well as isophotal, and total (MAG_AUTO and MAG_AUTO+correction). The catalogs also include SExtractor "stellarity" indices, half-light radii, ellipticities and position angles. SExtractor version 2.2.2 was used for the EDisCS photometry.
The magnitude limits used for this catalog are mtotalI <= 24.0 for mid-z clusters and mtotalI <= 24.5 for high-z clusters.
Zeropoint errors computed from rms dispersions in standard star measurements are 0.018 in B, 0.013 in V, 0.013 in R and 0.016 in I. These zeropoint errors are NOT included in the errors presented in this catalog, and they should therefore be added in quadrature to errors in catalog to obtain the full photometric errors.
The FORS2 filters B, V and I are close approximations to the Bessel (1990PASP..102.1181B) photometric system while R filter is a special filter for FORS2 (see http://www.eso.org/instruments/fors/inst/Filters/curves.html ).
