The VLSS data, at a frequency of 74 MHz cover 95% of the 3π sr of sky area above -30° declination. The original data have been reprocessed to create a revised version of the survey, called the VLSS redux (VLSSr). This reprocessing lead to substantial improvements allowing to release images of six unpublished fields and reducing the clean bias by 50%. The angular resolution is approximately 80“ and units of the data are Jy/Beam.
