Description


The Westerbork Northern Sky Survey (<i>WENSS</i>) 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''. <p> 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/"><i>WENSS</i> website</a>. <p> The <i>WENSS</i> survey is included on the <b>SkyView High Resolution Radio Coverage </b><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. <p> Provenance: <i>WENSS</i> Team.
