COSMOS VLA 327 MHz Catalog Column Descriptions
Overview
The 90 cm Very Large Array imaging of the COSMOS field comprises a circular area of 3.14 square degrees at 8.0 arcsec by 6.0 arcsec angular resolution with an average rms
of 0.5 mJy/beam. The extracted catalogue contains 182 sources (down to 5.5 sigma), 30 of which are multicomponent sources. If you use this catalog please cite
