cds-question@unistra.frsurveysgalaxy-planesmilky-way-galaxymillimeter-astronomysubmillimeter-astronomygalaxy-classification-systemsWe present early results from the JCMT (James Clerk Maxwell Telescope) Plane Survey (JPS), which has surveyed the northern inner Galactic plane between longitudes l=7{deg} and l=63{deg} in the 850-{mu}m continuum with SCUBA-2 (Submm Common-User Bolometer Array 2), as part of the JCMT Legacy Survey programme. Data from the l=30{deg} survey region, which contains the massive-star-forming regions W43 and G29.96, are analysed after approximately 40 percent of the observations had been completed. The pixel-to-pixel noise is found to be 19mJy/beam after a smooth over the beam area, and the projected equivalent noise levels in the final survey are expected to be around 10mJy/beam. An initial extraction of compact sources was performed using the FellWalker method, resulting in the detection of 1029 sources above a 5{sigma} surface-brightness threshold. The completeness limits in these data are estimated to be around 0.2Jy/beam (peak flux density) and 0.8 Jy (integrated flux density) and are therefore probably already dominated by source confusion in this relatively crowded section of the survey. The flux densities of extracted compact sources are consistent with those of matching detections in the shallower APEX (Atacama Pathfinder Experiment) Telescope Large Area Survey of the Galaxy (ATLASGAL) survey. We analyse the virial and evolutionary state of the detected clumps in the W43 star-forming complex and find that they appear younger than the Galactic-plane average.2015MNRAS.453.4264Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/453/4264CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/453/4264https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/453/4264http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/453/4264https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/453/4264https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/453/4264http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/453/4264GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/453/4264/table1 (The JPS l=30{deg} preliminary compact source catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/453/4264/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/453/4264/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/453/4264/table1?GETtext/xml+votable180.050000true280.25451-5.523740.0055555555555555565/7564 6/30223 30244-30245 30247 30260 30262-30263 30265 30268-30269 30306 30312-303142.3390025583187276e-22 2.3390025583187276e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/453/4264?format=asciiOpticalMillimeterdefaultJ/MNRAS/453/4264/table1The JPS l=30{deg} preliminary compact source cataloguerecnoRecord number assigned by the VizieR team.
