Beginning of ReadMe : J/ApJ/660/239 MaxBCG catalog of 13823 galaxy clusters from SDSS (Koester+, 2007) ================================================================================ A MaxBCG catalog of 13,823 galaxy clusters from the Sloan Digital Sky Survey.

This catalog includes 13823 clusters with velocity dispersions greater than  400km/s and is the largest galaxy cluster catalog assembled to date. They are selected in an approximately volume-limited way from a 0.5Gpc^3^ region covering 7500deg^2^ of sky between redshifts 0.1 and 0.3. Each cluster contains between 10 and 190 E/S0 ridgeline galaxies brighter than 0.4L* within a scaled radius R_200_. Description: Data for this study are drawn from the Sloan Digital Sky Survey a combined imaging and spectroscopic survey of 104deg^2^ in the north Galactic cap and a smaller region in the south. The imaging survey was carried out using a specially designed 2.5m telescope in drift-scan mode in five SDSS filters (u, g, r, i, and z) to a limiting magnitude of r<22.5. The maxBCG galaxy cluster selection algorithm applied to the input galaxy catalog is described in more detail in a companion paper (Koester et al., 2007ApJ...660..221K).
