Catalog of clusters of galaxies from SDSS
Listed in IVOA Registry (Virtual Observatory)
We present a catalog of 799 clusters of galaxies in the redshift range z_est_=0.05-0.3 selected from ~400deg^2^ of early Sloan Digital Sky Survey (SDSS) commissioning data along the celestial equator.
Description
The catalog is based on merging two independent selection methods - a color-magnitude red-sequence maxBCG technique (B), and a hybrid matched filter method (H). The BH catalog includes clusters with richness {Lambda}>=40 (matched filter) and Ngal>=13 (maxBCG), corresponding to typical velocity dispersion of {sigma}_v_>~400km/s and mass (within 0.6h^-1^Mpc radius) >~5x10^13^h^-1^M_{sun}_.
This threshold is below Abell richness class 0 clusters. The average space density of these clusters is 2x10^-5^h^3^/Mpc^3^. All NORAS (<J/ApJS/129/435>) X-ray clusters and 53 of the 58 Abell clusters in the survey region are detected in the catalog; the five additional Abell clusters are detected below the BH catalog cuts.

The cluster richness function is determined and found to exhibit a steeply decreasing cluster abundance with increasing richness. We derive observational scaling relations between cluster richness and observed cluster luminosity and cluster velocity dispersion; these scaling relations provide important physical calibrations for the clusters. The catalog can be used for studies of individual clusters, for comparisons with other sources such as X-ray clusters and active galactic nuclei, and, with proper correction for the relevant selection functions, also for statistical analyses of clusters.
