| Description: ! The Westerbork Northern Sky Survey (iWENSS/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 "http://www.strw.leidenuniv.nl/wenss" iWENSS/i web site/a. p The iWENSS/i survey is included on the bSkyView High Resolution Radio Coverage /b"http://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 ]] |
