The Second Planck Catalogue of Compact Sources (PCCS2) is a list of discrete Galactic and extragalactic objects detected across the entire sky by the European Space Agency's Planck mission. It supersedes previous catalogs and includes polarization measurements from seven sensitive channels. The catalog was produced by the Planck Low Frequency Instrument Data Processing Center and released by NASA.
A 1996 November Very Large Array (VLA) survey at 1.4 GHz of the Hubble Deep Field region, totaling 50 hours of observation. The catalog contains 371 radio sources detected within 20 arcminutes of the field center, with a formal completeness limit of 40 microJansky. This table was created by NASA's HEASARC in June 2012 based on the original CDS catalog.
The full-duration Planck mission (2009 onward) produced the Second Planck Catalogue of Compact Sources (PCCS2), a list of discrete Galactic and extragalactic objects detected across the entire sky. It was created by the European Space Agency (ESA) with NASA contributions, superseding earlier versions with improved processing and reduced noise. The catalog includes polarization measurements for seven sensitive channels and aims for 80% integral reliability.
20,719 infrared-excess sources identified across 18 massive star-forming complexes in the Milky Way, with distances ranging from 0.4 to 3.6 kiloparsecs. The MYStIX project, led by NASA, produced this catalog in 2013 to isolate 8,686 probable young stellar members from contaminants like evolved stars and nebular knots. Data combines photometry from Spitzer/IRAC, 2MASS, and UKIRT telescopes using spectral energy distribution fitting and spatial clustering.
Observations from 2012 onward by the NuSTAR telescope surveyed the Galactic Center region, discovering 70 hard X-ray point sources in a 0.6 square-degree area. The table, created by NASA HEASARC in March 2018, includes source identifications, luminosity data, and spectral analysis suggesting a large fraction of magnetic cataclysmic variables. It covers a total exposure of 1.7 Ms in the central region and 300 ks in the Sgr B2 field.
1,874 stellar objects with ultraviolet excess were cataloged from photographic plates taken with the Palomar 18-inch Schmidt telescope. The catalog provides positions, magnitudes, spectral types, and color data, with a statistically complete sample of 1,715 objects covering 10,714 square degrees. NASA HEASARC hosts this version, which includes updates from 2009 providing more precise coordinates.
719 galaxies within 50 megaparsecs were surveyed using Chandra X-ray Observatory data as of March 2016. The survey identified 314 X-ray active galactic nuclei, with a typical photon index of around 1.8. This table was created by the HEASARC in September 2017 based on catalog files from the CDS.
The Planck Catalog of Compact Sources Release 2 (PCCS2) is a list of discrete astronomical objects detected across the entire sky by the European Space Agency's Planck mission. It supersedes previous catalogs and includes both Galactic and extragalactic sources detected in single-frequency maps from the full mission duration. The catalog provides polarization measurements for seven sensitive channels and is divided into the PCCS2 and PCCS2E subcatalogs based on source location and reliability.
NASA HEASARC provides the Giant Metrewave Radio Telescope 240-MHz source catalog for the XMM-Large Scale Structure field. The catalog contains 571 entries, comprising 388 single sources and 183 components of multiple sources, derived from observations reaching a noise level of ~2.5 mJy/beam. This table was created by the HEASARC in February 2012 based on the source catalog J/A+A/471/1105.
0.62 million radio sources were cataloged from the TIFR GMRT Sky Survey (TGSS) covering 90% of the sky. The Giant Metrewave Radio Telescope (GMRT) collected over 2000 hours of observations between April 2010 and March 2012. The HEASARC created this table in February 2017 based on data from the TGSS Alternative Data Release project.
468 radio sources were detected with the Very Long Baseline Array (VLBA) from an input catalog of 2,865 known sources in the Cosmic Evolution Survey (COSMOS) field. This table contains 504 entries, including the 468 VLBA-detected sources and individual components for multi-component sources, compiled by the National Aeronautics and Space Administration. The catalog's primary purpose is to serve as an AGN catalog and includes complementary multiwavelength (optical, infrared, X-ray) information for the detected sources.
A 2005 Chandra X-ray observation combined with multi-epoch VISTA near-infrared photometry provides a catalog of 2148 probable stellar members in the young cluster NGC 6231. This catalog, which is 70% larger than previous censuses, includes low-mass stars and B stars with newly identified X-ray counterparts. The work estimates a total population of 5700-7500 members down to 0.08 solar masses within the Chandra field.
Nearly 4000 discrete compact radio sources detected in the Galactic plane by the Westerbork Synthesis Radio Telescope. The survey covers a section from +42 to +92 degrees Galactic Longitude, observed at two epochs to identify variable sources. The catalog, produced by the National Aeronautics and Space Administration, lists source positions, flux densities, and dimensions for objects with peak intensity >5 times the local noise level.
NASA's Chandra X-ray Observatory performed a 71-ksec observation of the young stellar cluster NGC 3293 in October 2015, detecting 1026 individual X-ray point sources. The data were used to characterize the cluster's low-mass stellar population, refute claims of a mass function deficit, and estimate an age of 8-10 million years. The catalog includes identified counterparts for 74% of the X-ray sources from deep near-infrared images.
The Second Planck Catalogue of Compact Sources (PCCS2) lists discrete Galactic and extragalactic objects detected across the entire sky from the full duration of the Planck mission, which operated from 2009. It supersedes earlier versions and includes sources detected at frequencies from 30 to 857 GHz, with polarization data for seven channels. The catalog was produced by the European Space Agency (ESA) and NASA, with contributions from the Low Frequency Instrument Data Processing Center.
Planck, a European Space Agency mission launched in 2009, mapped the entire sky at frequencies from 30 to 857 GHz. The Second Planck Catalogue of Compact Sources (PCCS2) lists discrete Galactic and extragalactic objects detected in these full-mission maps, superseding earlier versions. It includes polarization measurements for seven channels and is split into the PCCS2 and PCCS2E subcatalogs based on detection reliability in different sky regions.
