cds-question@unistra.fropen-star-clustersccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe derive cluster parameters and mass functions from new UBVRI CCD photometric observations of ~3500 stars reaching down to V~20mag for the distant southern open star clusters NGC 3105, NGC 3603, Melotte 105, Hogg 15, NGC 4815, Pismis 20 and NGC 6253. For NGC 3105 and Hogg 15, CCD data are presented for the first time. The observations were carried out in 1992 between February 28 and March 8, June 5 and 9, and July 9 and 12 in the Cousins U, B, V, R and I photometric bands using CCD detector at the 1.0-m Elizabeth Telescope at the South African Astronomical Observatory (SAAO), Sutherland.2001MNRAS.327...23Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/327/23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/111/85 : Open cluster Pis 20 (Vazquez+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/327/23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/327/23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/327/23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/327/23https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/327/23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/327/23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/327/23/table1 (Preliminary information about the clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/327/23/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/327/23/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/327/23/table1?GETtext/xml+votable180.050000true150.187-54.77840.0055555555555555566/37237 37375 37924 41649 41758 42177 43024https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/327/23?format=asciiOpticalInfrareddefaultJ/MNRAS/327/23/table1Preliminary information about the clustersOClOCl numbermeta.idintrecnoRecord number assigned by the VizieR team.
