VLA Faint Images of the Radio Sky at Twenty Centimeters (FIRST)

Faint Images of the Radio Sky at Twenty-cm (FIRST) is a systematic survey of the North and South Galactic caps begun in 1993, using the NRAO Very Large Array (VLA) . Typical images are comprised of 1150x1550 1.8" pixels with 5" resolution. Source catalogs are also available including peak and integrated flux densities generated from the high resolution coadded images. The survey yields very accurate (1 mJy/beam) compact sources. The areas observed were chosen to coincide with the Sloan Digital Sky Survey.
