cds-question@unistra.fropen-star-clustersradial-velocityThe spiral structure of the Milky Way (MW) is highly uncertain and is the subject of much discussion nowadays. Even the spiral structure close to the Sun and the real nature of the so-called Local or Orion arm are poorly known. We present the first result from a program that determines the properties of the Local (Orion) spiral arm (LOA), together with a full description of the program. In this context we have made a comprehensive study of the young LOA open cluster NGC 2302, which includes a UBVRI photometric analysis and determination of its kinematic properties - proper motion (PM) and radial velocity (RV) - and of its orbital parameters.2015A&A...580A...4Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/580/A4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/322 : UCAC4 Catalogue (Zacharias+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/580/A4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/580/A4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/580/A4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/580/A4https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/580/A4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/580/A4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/580/A4/table2 (Radial velocities of 74 stars in NGC 2302 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/580/A4/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/580/A4/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/580/A4/table2?GETtext/xml+votable180.050000true102.8961667-6.99302780.0055555555555555566/22021https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/580/A4?format=asciiOpticaldefaultJ/A+A/580/A4/table2Radial velocities of 74 stars in NGC 2302 fieldSimbadNameSimbad column added by the CDSmeta.idcharSeq[1/74] Sequential numbermeta.recordintprimaryRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainDEJ2000Declination (J2000)pos.eq.dec;meta.mainRV[-30/106] Radial velocitykm/sphys.veloc;pos.heliocentricfloate_RV[1/7.2] rms uncertainty on RVkm/sstat.errorfloato_RV7/23] Number of RV determinations leading to RV and e_RVmeta.numberintPM[UCAC4] Indicates if the star has a proper motion value in the UCAC4 Catalog (I/322)meta.ref.urlchar
