Monte Carlo simulations indicate that the false-detection rate of our detecting method is about 3.1%. The total masses of galaxy clusters are derived using a calibrated richness-mass relation that is based on the observations of X-ray emission and the Sunyaev and Zel'dovich effect. The median redshift and mass of our detected clusters are about 0.53 and 1.23x10^14^M_{sun}_, respectively. Comparing with previous clusters identified using the data of the Sloan Digital Sky Survey; we can recognize most of them, especially those with high richness. Our catalog will be used for further statistical studies on galaxy clusters and environmental effects on galaxy evolution, etc. 2021ApJS..253...56Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/253/56 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to VII/110 : Rich Clusters of Galaxies (Abell+ 1989) J/ApJ/660/239 : MaxBCG catalog of galaxy clusters from SDSS (Koester+, 2007) J/ApJS/191/254 : GMBCG galaxy cluster catalog from SDSS DR7 (Hao+, 2010) J/A+A/534/A109 : MCXC Meta-Catalogue X-ray galaxy Clusters (Piffaretti+, 2011) J/ApJ/736/21 : Galaxy clusters opt. cat. from AMF on SDSS DR6 (Szabo+ 2011) J/ApJ/734/68 : High redshift galaxy clusters in deep fields (Wen+, 2011) J/ApJS/199/34 : Clusters of galaxies in SDSS-III (Wen+, 2012) J/ApJ/763/127 : Galaxy clusters in the SPT survey (Reichardt+, 2013) J/A+A/558/A75 : 2XMMi/SDSS Galaxy Cluster Survey.
