Jansky Very Large Array. We obtained 1000hr of L-band ({lambda}=20cm) observations across four spectral windows (SPWs; 1.063-1.831GHz) in a single pointing and produced a confusion-limited image with an apparent rms noise of 1.67uJy/beam with a synthesized beam of 5.5"x5.0". This paper reports a 1.4GHz radio continuum source catalog containing 1678 sources detected above 7{sigma} (flux densities greater than 11.7uJy), identified using two independent source extraction programs applied to the Stokes I image. Resolved sources dominate at flux density S_1.4GHz_>=42uJy. The radio spectral index for each source was derived using a power-law fit across the four SPWs, and we found that a robust spectral index measurement requires a total signal-to-noise ratio of at least 20. Comparisons with previous 1.4GHz radio continuum surveys show good overall consistency, but evidence for a high degree of catalog incompleteness and the effects of source confusion are evident for some of the earlier studies.2025AJ....170...60Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/170/60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/554/803 : New VLA Sky Survey (NVSS) Cat of IRAS 2 Jy Galaxies (Yun+ 2001)J/ApJ/586/794 : Multiwavelength luminosities of galaxies (Bell, 2003)J/A+A/403/857 : VLA-VIRMOS Deep Field (Bondi+, 2003)J/A+A/398/901 : VLA survey at 6 cm in the Lockman Hole (Ciliegi+, 2003)J/A+A/457/517 : ATESP 5 GHz radio survey.
