cds-question@unistra.fropen-star-clustersccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe present CCD BVI photometry for the southern open cluster NGC 2489 and its surrounding field. The sample consists of 2182 stars measured in an area of 13.6'x13.6', extending down to V~21.5. These data are supplemented with CORAVEL radial-velocity observations for seven red giant candidates. A cluster angular radius of 6.7+/-0.6', equivalent to 3.5+/-0.3pc, is estimated from star counts carried out inside and outside the cluster region. The comparison of the cluster colour-magnitude diagrams with isochrones of the Padova group yields E(B-V)=0.30+/-0.05, E(V-I)=0.40+/-0.05 and V-MV=12.20+/-0.25 for logt=8.70 (t=500^+130^_-100_Myr) and Z=0.019. NGC 2489 is then located at 1.8+/-0.3kpc from the Sun and 25pc below the Galactic plane. The analysis of the kinematical data allowed us to confirm cluster membership for six red giants, one of them being a spectroscopic binary. A mean radial velocity of 38.13+/-0.33km/s was derived for the cluster red giants. The properties of a sample of open clusters aligned along the line of sight of NGC 2489 are examined.2007MNRAS.377.1737Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/377/1737CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/373/153 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/377/1737https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/377/1737http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/377/1737https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/377/1737https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/377/1737http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/377/1737GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/377/1737/table1 (CCD BVI data of stars in the field of NGC 2489)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/377/1737/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/377/1737/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/377/1737/table1?GETtext/xml+votable180.050000true119.01475694-29.929047780.0055555555555555566/39770https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/377/1737?format=asciiOpticalInfrareddefaultJ/MNRAS/377/1737/table1CCD BVI data of stars in the field of NGC 2489recnoRecord number assigned by the VizieR team.
