Description

The Westerbork Northern Sky Survey (WENSS) is a low-frequency radio survey that covers the whole sky north of delta=30 degree at a wavelength of 92 cm to a limiting flux density of approximately 18 mJy (5 sigma). This survey has a resolution of 54" x 54" cosec (delta) and a positional accuracy for strong sources of 1.5''. Further information on the survey including links to catalogs derived from the survey is available at the <a href="https://web.archive.org/web/20041204180313/http://www.strw.leidenuniv.nl/wenss/">WENSS website</a>. The WENSS survey is included on the SkyView High Resolution Radio Coverage <a href="https://skyview.gsfc.nasa.gov/images/high_res_radio.jpg"> map</a>. This map shows coverage on an Aitoff projection of the sky in equatorial coordinates. Provenance: WENSS Team.
