cds-question@unistra.frradio-galaxiesradio-sourcesBrightness-weighted differential source counts S2n(S) spanning the eight decades of flux density between 0.25{mu}Jy and 25Jy at 1.4GHz were measured from (1) the confusion brightness distribution in the MeerKAT DEEP2 image below 10{mu}Jy, (2) counts of DEEP2 sources between 10{mu}Jy and 2.5mJy, and (3) counts of NVSS sources stronger than 2.5mJy. We present our DEEP2 catalog of 1.7x10^4^ discrete sources complete above S=10{mu}Jy over {Omega}=1.04deg^2^. The brightness-weighted counts converge as S^2^n(S){propto}S^1/2^ below S=10{mu}Jy, so >99% of the {Delta}T_b_~0.06K sky brightness produced by active galactic nuclei and ~96% of the {Delta}T_b_~0.04K added by star-forming galaxies has been resolved into sources with S>=0.25{mu}Jy. The {Delta}T_b_~0.4K excess brightness measured by ARCADE 2 cannot be produced by faint sources smaller than ~50kpc if they cluster like galaxies.2021ApJ...909..193Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/909/193CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/AJ/77/405 : Intense radio sources at 1400MHz (BDFL set) (Bridle+, 1972)J/AJ/125/465 : Phoenix Deep Survey 1.4-GHz microJy Catalog (Hopkins+, 2003)J/AJ/132/1729 : HUDF BVI-dropout sources (Beckwith+, 2006)J/AJ/136/1889 : 20cm observations of deep Swire Field (Owen+, 2008)J/ApJS/188/178 : VLA 1.4GHz obs. of GOODS-North field (Morrison+, 2010)J/A+A/602/A1 : VLA-COSMOS 3 GHz Large Project (Smolcic+, 2017)J/ApJ/856/67 : VLA 3GHz radio sources in the Lockman Hole (Cotton+, 2018)J/ApJS/235/34 : Deep JVLA imaging of GOODS-N at 20cm (Owen, 2018)J/MNRAS/481/4548 : Constraints on the 1.4GHz source counts (Prandoni+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/909/193https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/909/193http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/909/193https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/909/193https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/909/193http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/909/193GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/909/193/table3 (The 1.266GHz DEEP2 component catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/909/193/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/909/193/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/909/193/table3?GETtext/xml+votable180.050000true60.038925-80.026077780.005555555555555556Cone search capability for table J/ApJ/909/193/table4 (DEEP2 multicomponent sources (section 5.3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/909/193/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/909/193/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/909/193/table4?GETtext/xml+votable180.050000true60.196-79.85872220.0055555555555555566/32842-32843 32846 32864-32865 328688.388604290859761e-25 8.388604290859761e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/909/193?format=asciiRadiodefaultJ/ApJ/909/193/table3The 1.266GHz DEEP2 component catalogGroupMulticomponent source group label (G01 to G35)meta.id.parentcharrecnoRecord number assigned by the VizieR team.
