cds-question@unistra.frradio-sourcesinfrared-photometryThe Very Large Array has been used in C configuration to map an area ~=0.3deg^2^ at 1.4GHz with 5{sigma} sensitivities of 0.305, 0.325, 0.380, and 0.450mJy/beam over four equal subareas. Radio properties are presented for 62 detected sources. Deep optical imaging to Gunn r ~=25mag using the Hale 5m telescope covering ~=0.21deg^2^ is reported for a subset of 43 sources. This optical follow-up is much deeper than that of existing larger area radio surveys of similar radio sensitivity. Archival J-, H-, and K-band photometry from the Two-Micron All Sky Survey is also presented. Using a robust likelihood ratio technique, we optically identified 26 radio sources with probability >~80%, nine with uncertain/ambiguous detections, and eight with empty fields. Comparisons with a stellar synthesis model that includes radio emission and dust reddening suggest that the near-infrared-optical emission in a small, bright subsample is reddened by "optically thin" dust with absorption A_V_~=22.5mag, regardless of morphological type. This is consistent with other, more direct determinations of absorption. The radio-optical(-near-infrared) flux ratios of early-type galaxies require significant contamination in the radio by an active galactic nucleus, consistent with the current paradigm. Using our simple modeling approach, we also discuss a potential diagnostic for selecting ultraluminous infrared galaxies to z~=1.6 from microJansky radio surveys.2001PASP..113...10Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/113/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/113/10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/113/10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/113/10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/113/10https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/113/10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/113/10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/113/10/table2 (Catalog of radio source data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/113/10/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/113/10/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/113/10/table2?GETtext/xml+votable180.050000true2.9919083325.840113890.005555555555555556Cone search capability for table J/PASP/113/10/table3 (Complete sample of sub-mJy radio sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/113/10/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/113/10/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/113/10/table3?GETtext/xml+votable180.050000true3.06887526.025769440.0055555555555555566/20252-20253 20255https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/113/10?format=asciiInfraredRadiodefaultJ/PASP/113/10/table2Catalog of radio source dataPAPosition angledegpos.posAngintrecnoRecord number assigned by the VizieR team.
