Resampled in Healpix by CDS. The Westerbork Northern Sky Survey (WENSS) is a low-frequency radio survey, designed to cover the whole sky north of declination 30deg at a wavelength of 92 cm (325  MHz), and about a quarter of this region, concentrated at high galactic latitudes, at a wavelength of 49 cm (609  MHz), to a limiting flux density of approximately 18 mJy and 15 mJy respectively. Observations for WENSS were carried out with the WSRT (The Westerbork Synthesis Radio Telescope) in a standard  set-up.Original acknowledgement for data: We have made use of the WSRT on the Web Archive. The Westerbork Synthesis Radio Telescope is operated by the Netherlands Institute for Radio Astronomy ASTRON, with support of NWO</description><source format="bibcode">1997A&amp;AS..124..259R</source><referenceURL>https://alasky.cds.unistra.fr/WENSS</referenceURL><type>Survey</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsDerivedFrom</relationshipType><relatedResource>ASTRON</relatedResource></relationship></content><rights rightsURI="https://cds.unistra.fr/aladin-org/licences_aladin.html">This HiPS is distributed under ODbL license by Unistra/CNRS</rights><capability standardID="ivo://ivoa.net/std/hips#hips-1.0"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="base">https://alasky.cds.unistra.fr/WENSS</accessURL><mirrorURL>https://alaskybis.cds.unistra.fr/WENSS</mirrorURL><mirrorURL>http://skies.esac.esa.int/WENSS</mirrorURL></interface></capability><coverage><temporal>48316 50447</temporal><spectral>2.159180279509705e-25 2.159180279509705e-25</spectral><footprint ivo-id="ivo://mocivod">https://alasky.cds.unistra.fr/WENSS/Moc.fits</footprint><waveband>Radio</waveband></coverage></ri:Resource>
