This database table presents the catalog of emissive point-sources detected in the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) survey, which is a contiguous 2530 deg² area surveyed between 2008-2011 in three bands centered at 95, 150, and 220 GHz. The catalog contains 4845 sources measured at a significance of 4.5 sigma or greater in at least one band, corresponding to detections above approximately 9.8, 5.8, and 20.4 mJy in 95, 150, and 220 GHz, respectively. Spectral behavior in the SPT bands is used for source classification into two populations based on the underlying physical mechanisms of compact, emissive sources that are bright at millimeter wavelengths: synchrotron radiation from active galactic nuclei and thermal emission from dust. The latter population includes a component of high-redshift sources often referred to as submillimeter galaxies (SMGs). In the relatively bright flux ranges probed by the survey, these sources are expected to be magnified by strong gravitational lensing. The survey also contains sources consistent with protoclusters, groups of dusty galaxies at high redshift undergoing collapse. The authors cross-match the SPT-SZ catalog with external catalogs at radio, infrared, and X-ray wavelengths and identify available redshift information. The catalog splits into 3980 synchrotron-dominated and 865 dust-dominated sources and determines a list of 506 SMGs. 10 sources are identified as stars. The SPT is a 10-m telescope located at the Amundsen-Scott South Pole station in Antarctica. At 150 GHz (2 mm), the SPT has arcminute angular resolution and a 1 deg² diffraction-limited field of view. The SPT was designed for high-sensitivity millimeter/sub-millimeter observations of faint, low-contrast sources, such as CMB anisotropies. The first survey with the SPT, designated as the SPT-SZ survey, was completed in 2011 November and covers a ~2500 deg² region of the southern extragalactic sky in three frequency bands, 95, 150, and 220 GHz, corresponding to wavelengths of 3.2, 2.0, and 1.4 mm. The fields were surveyed to depths of approximately 40, 18, and 70 microK arcmin at 95, 150, and 220 GHz, respectively. This study uses data from 19 fields observed by the SPT between 2008 and 2011. The fields are referred to using the J2000 coordinates of their centers, Right Ascension in hours and Declination in degrees. Table 1 in the reference paper lists the positions and effective areas of these fields.The total effective area used for the catalog and analysis in this present work is 2530 deg². The catalog is an extension of two previous works: Vieira et al. (2010, ApJ, 719, 763) and Mocanu et al. (2013, ApJ, 779, 61) and builds on the same analysis pipeline, adding 1759 deg² of newly analyzed data, and additional data for two fields which were re-observed in 2010 and 2011. This table was originally created by the HEASARC in January 2014. It was updated to the 2020 version of this catalog in July 2020, based on a machine-readable catalog which was obtained from the <a href="https://lambda.gsfc.nasa.gov/product/spt/spt_everett2020_ps_catalog_info.cfm">LAMBDA</a> website.
