cds-question@unistra.frmilky-way-galaxyopen-star-clustersradial-velocityOpen clusters (OCs) are crucial for studying the formation and evolution of the Galactic disc. However, the lack of a large number of OCs analyzed homogeneously hampers the investigations about chemical patterns and the existence of Galactocentric radial and vertical gradients, or an age-metallicity relation. To overcome this, we have designed the Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO). We aim to provide homogeneous radial velocities, physical parameters and individual chemical abundances of six or more Red Clump stars for a sample of 25 old and intermediate-age OCs visible from the Northern hemisphere. To do so, we use high resolution spectroscopic facilities (R~62,000) available at Spanish observatories. We present the motivation, design and current status of the survey, together with the first data release of radial velocities for 77 stars in 12 OCs, which represents about 50% of the survey. We include clusters never studied with high-resolution spectroscopy before (NGC 1907, NGC 6991, NGC 7762), and clusters in common with other large spectroscopic surveys like the Gaia-ESO Survey (NGC 6705) and APOGEE (NGC 2682 and NGC 6819). We perform internal comparisons between instruments to evaluate and correct internal systematics of the results, and compare our radial velocities with previous determinations in the literature, when available. Finally, radial velocities for each cluster are used to perform a preliminar kinematic study in relation with the Galactic disc.2016MNRAS.458.3150Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/3150CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/ocl : Optically visible open clusters and Candidates (Dias+ 2002-15)III/55 : Radial Velocities in Open Clusters (Mermilliod 1979)III/97 : Radial Velocities in open clusters (Mermilliod 1984)III/254 : 2nd Cat. of Radial Velocities with Astrometric DataJ/A+A/345/471 : Memberships of open clusters (Robichon+, 1999)J/A+A/375/30 : Radial velocities in open clusters (Mermilliod+, 2001)J/A+A/438/1163 : Catalogue of Open Cluster Data (COCD) (Kharchenko+, 2005)J/ApJ/648/580 : Rotational velocities in 19 open clusters (Huang+, 2006)J/A+A/485/303 : Radial velocities for 1309 stars & 166 OCl (Mermilliod+, 2009)J/A+A/558/A53 : Milky Way global survey of star clusters II (Kharchenko+ 2013)J/PAZh/38/571 : Astrophysical parameters for 593 open clusters (Gozha+, 2012)J/A+A/562/A54 : Galactic open clusters in RAVE (Conrad+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/3150https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/3150http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/3150https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/3150https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/3150http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/3150GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/3150/table6 (*Final radial velocities and literature comparison)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/3150/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/3150/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/3150/table6?GETtext/xml+votable180.050000true213.915291719.18240830.0055555555555555566/1299 1302 2433 2436 4298 4574 8767 14175 14752-14753 15396 15709 15711 24522 30215 30439 30445 31812 40696https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/3150?format=asciidefaultJ/MNRAS/458/3150/table6*Final radial velocities and literature comparisonSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
