cds-question@unistra.frgalaxy-clustersredshiftedastronomical-object-identificationradio-sourcesvisible-astronomyWe present a catalog of 182 galaxy clusters detected through the Sunyaev-Zel'dovich (SZ) effect by the Atacama Cosmology Telescope in a contiguous 987.5deg^2^ field. The clusters were detected as SZ decrements by applying a matched filter to 148GHz maps that combine the original ACT equatorial survey with data from the first two observing seasons using the ACTPol receiver. Optical/IR confirmation and redshift measurements come from a combination of large public surveys and our own follow-up observations. Where necessary, we measured photometric redshifts for clusters using a pipeline that achieves accuracy {Delta}z/(1+z)=0.015 when tested on Sloan Digital Sky Survey data. Under the assumption that clusters can be described by the so-called universal pressure profile (UPP) and its associated mass scaling law, the full signal-to-noise ratio > 4 sample spans the mass range 1.6<M_500c_^UPP^/10^14^M_{sun}_<9.1, with median M_500c_^UPP^=3.1x10^14^M_{sun}_. The sample covers the redshift range 0.1<z<1.4 (median z=0.49), and 28 clusters are new discoveries (median z=0.80). We compare our catalog with other overlapping cluster samples selected using the SZ, optical, and X-ray wavelengths. We find that the ratio of the UPP-based SZ mass to richness-based weak-lensing mass is <M_500c_^UPP^>/<M_500c_^{lambda}WL^>=0.68+/-0.11. After applying this calibration, the mass distribution for clusters with M_500c_>4x10^14^M_{sun}_ is consistent with the number of such clusters found in the South Pole Telescope SZ survey.2018ApJS..235...20Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/235/20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)VIII/103 : Herschel Multi-tiered Extragalactic Survey (Oliver+, 2012)VIII/95 : Herschel Multi-tiered Extragalactic Survey (Oliver+, 2012)II/359 : The VISTA Hemisphere Survey (VHS) catalog DR4.1 (McMahon+, 2013)II/367 : The VISTA Hemisphere Survey (VHS) catalog DR5 (McMahon+, 2020)VIII/91 : Planck Catalog of Compact Sources Release 1 (Planck, 2013)J/MNRAS/274/75 : z of ROSAT X-ray brightest clusters (Crawford+, 1995)J/ApJS/129/435 : NORAS galaxy cluster survey.
