VLSSr - 74 MHz continuum survey collection
Listed in IVOA Registry (Virtual Observatory)
The VLA Low-Frequency Sky Survey Redux (VLSS) is a 74 MHz continuum survey covering the entire sky north of -30 degrees declination.
Description
Using the VLA in BnA and B-configurations, it will map the entire survey region at a resolution of 80" and with an average rms noise of 0.1 Jy/beam. This version include the data from the VLSS redux which increased the coverage region slightly and substantially improved the data reduction.
Details are in the Lane et al. (2012) reference. Frequency: 74 MHz, PixelUnits: Janskies/Beam. The VLSSr represents a major improvement to the original VLSS over most of the sky.

It includes six previously unpublished fields, and improved dynamic range in 95% of all fields. The clean bias has been halved and is now 0.66 times the local RMS. The largest angular size imaged has been roughly doubled to 36', and the number of cataloged sources is increased by 35% to %93,000.Original acknowledgement for data: Radio Science v. 47, RS0K04
