JPS is an 850-{mu}m continuum survey of six fields in the northern inner Galactic plane in a longitude range of l=7{deg}-63{deg}, made with the Submillimetre Common-User Bolometer Array 2. This first data release consists of emission maps of the six JPS regions with an average pixel-to-pixel noise of 7.19mJy/beam, when smoothed over the beam, and a compact source catalogue containing 7813 sources. The 95 per cent completeness limits of the catalogue are estimated at 0.04Jy/beam and 0.3Jy for the peak and integrated flux densities, respectively. The emission contained in the compact source catalogue is 42+/-5 per cent of the total and, apart from the large-scale (greater than 8 arcmin) emission, there is excellent correspondence with features in the 500-{mu}m Herschel maps. We find that, with two-dimensional matching, 98 {\pm} 2 per cent of sources within the fields centred at l=20{deg}, 30{deg}, 40{deg} and 50{deg} are associated with molecular clouds, with 91+/-3 per cent of the l=30{deg} and 40{deg} sources associated with dense molecular clumps. Matching the JPS catalogue to Herschel 70-{mu}m sources, we find that 38+/-1 per cent of sources show evidence of ongoing star formation. The JPS Public Release 1 images and catalogue will be a valuable resource for studies of star formation in the Galaxy and the role of environment and spiral arms in the star formation process.surveysgalaxy-planesmilky-way-galaxymillimeter-astronomysubmillimeter-astronomygalactic-and-extragalactic-astronomyobservational-astronomyhttps://dc.g-vo.org/rr/q/lp/custom/CDS.VizieR/J/MNRAS/469/2163http://doi.org/10.26093/cds/vizier.74692163https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/469/21632017MNRAS.469.2163Ehttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/469/2163Cone search capability for table J/MNRAS/469/2163/table2 (JPSPR1 compact source catalogue)Eden D.J.Moore T.J.T.Plume R.Urquhart J.S.Thompson M.A.,Parsons H.Dempsey J.T.Rigby A.J.Morgan L.K.Thomas H.S.Berry D.,Buckle J.Brunt C.M.Butner H.M.Carretero D.Chrysostomou A.,Currie M.J.Devilliers H.M.Fich M.Gibb A.G.Hoare M.G.Jenness T.,Manser G.Mottram J.C.Natario C.Olguin F.Peretto N.Pestalozzi M.,Polychroni D.Redman R.O.Salji C.Summers L.J.Tahani K.,Traficante A.Difrancesco J.Evans A.Fuller G.A.Johnstone D.,Joncas G.Longmore S.N.Martin P.G.Richer J.S.Weferling B.,White G.J.Zhu M.CDS2020https://cds.unistra.fr/vizier-org/licences_vizier.htmlCDS support team <cds-question@unistra.fr>DatasetAstroObjectsastronomy
