cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryproper-motionsWe present UBVRI photometry of stars in the field of the intermediate-age open cluster NGC 559. By determining the stellar membership probabilities derived through a photometric and kinematic study of the cluster, we identify the 22 most probable cluster members. These are used to obtain robust cluster parameters. The mean proper motion of the cluster is {mu}_x_=-3.29+/-0.35, {mu}_y_=-1.24+/-0.28mas/yr. The radial distribution of the stellar surface density gives a cluster radius of 4.5+/-0.2arcmin (3.2+/-0.2pc). By fitting solar metallicity stellar isochrones to the colour-colour and colour-magnitude diagrams, we find a uniform cluster reddening of E(B-V)=0.82+/-0.02. The cluster has an age of 224+/-25Myr and is at a distance of 2.43+/-0.23kpc. From the optical and near-infrared two-colour diagrams, we obtain colour excesses in the direction of the cluster E(V-K)=2.14+/-0.02, E(J-K)=0.37+/-0.01 and E(B-V)=0.76+/-0.04. A total-to-selective extinction of R_V_=3.5+/-0.1 is found in the direction of the cluster which is marginally higher than the normal value. We derive the luminosity function and the mass function for the cluster main sequence. The mass function slope is found to be -2.12+/-0.31. We find evidence of mass segregation in this dynamically relaxed cluster.2014MNRAS.437..804Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/437/804CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/419/2379 : NGC 6866 variables V and I light curves (Joshi+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/437/804https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/437/804http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/437/804https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/437/804https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/437/804http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/437/804GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/437/804/table4 (Photometric catalogue of 2293 stars detected in the field of cluster NGC 559)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/437/804/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/437/804/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/437/804/table4?GETtext/xml+votable180.050000true22.300791763.34113890.0055555555555555566/3640-36428.650015785639275e-20 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/437/804?format=asciiOpticalInfrareddefaultJ/MNRAS/437/804/table4Photometric catalogue of 2293 stars detected in the field of cluster NGC 559Seq[1/2393] Sequential numbermeta.recordintprimaryRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainDEJ2000Declination (J2000)pos.eq.dec;meta.mainUmag?
