cds-question@unistra.frsurveysgalaxy-clustersh-i-line-emissionradio-astronomyWe present results of a blind 21cm HI-line imaging survey of a galaxy overdensity located behind the Milky Way at l, b ~= 160{deg}, 0.5{deg}. The overdensity corresponds to a zone-of-avoidance crossing of the Perseus-Pisces Supercluster filament. Although it is known that this filament contains an X-ray galaxy cluster (3C 129) hosting two strong radio galaxies, little is known about galaxies associated with this potentially rich cluster because of the high Galactic dust extinction. We mapped a sky area of ~9.6 deg^2^ using the Westerbork Synthesis Radio Telescope in a hexagonal mosaic of 35 pointings observed for 12h each, in the radial velocity range cz=2400-16600km/s. The survey has a sensitivity of 0.36mJy/beam rms at a velocity resolution of 16.5km/s. We detected 211 galaxies, 62 per cent of which have a near-infrared counterpart in the UKIDSS Galactic Plane Survey. We present a catalogue of the HI properties and an HI atlas containing total intensity maps, position-velocity diagrams, global HI profiles and UKIDSS counterpart images. For the resolved galaxies we also present HI velocity fields and radial HI surface density profiles. A brief analysis of the structures outlined by these galaxies finds that 87 of them lie at the distance of the Perseus-Pisces Supercluster (cz~4000-8000km/s) and seem to form part of the 3C 129 cluster. Further 72 detections trace an overdensity at a velocity of cz~=10000km/s and seem to coincide with a structure predicted from mass density reconstructions in the first 2MASS Redshift Survey.2016MNRAS.460..923Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/460/923CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/460/923https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/460/923http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/460/923https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/460/923https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/460/923http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/460/923GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/460/923/table1 (Observing parameters of the WSRT PP ZoA survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/923/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/923/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/923/table1?GETtext/xml+votable180.050000true72.395208345.04246940.005555555555555556Cone search capability for table J/MNRAS/460/923/tablea1 (Catalogue for resolved galaxy detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/923/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/923/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/923/tablea1?GETtext/xml+votable180.050000true71.113208345.85463890.005555555555555556Cone search capability for table J/MNRAS/460/923/tablea2 (Marginally resolved galaxy detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/460/923/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/460/923/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/460/923/tablea2?GETtext/xml+votable180.050000true71.350583345.32341670.0055555555555555565/366 6/1453 1455 1459-1460 1462 1468 1470 1797 1799 1808-1810 1812https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/460/923?format=asciiRadiodefaultJ/MNRAS/460/923/table1Observing parameters of the WSRT PP ZoA surveyrecnoRecord number assigned by the VizieR team.
