cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryCCD BVI photometry of the faint open clusters Berkeley 73, Berkeley 75 and Berkeley 25 are presented. The two latter are previously unstudied clusters to our knowledge. While Berkeley 73 is found to be of intermediate-age (about 1.5Gyr old), Berkeley 75 and Berkeley 25 are old clusters, with ages greater than 3.0Gyr. We provide also estimates of the clusters size. All these clusters lie far away from the Galactic Center, at R_GC_>=16kpc, and quite high on the Galactic plane, at |Z_{sun}_|>=1.5kpc. They are therefore important targets to probe the properties of the structure of the Galaxy in this direction, where the Canis Major over-density has been discovered to be located.2005A&A...442..917Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/442/917CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/429/607 : BV photometry of Berkeley 36, 73 and 34 (Ortolani+, 2005)J/A+A/372/71 : King 5 and Berkeley 20 UBVRI photometry (Durgapal+, 2001)J/A+A/372/879 : JKBV photometry of NGC 2141 (Carraro+, 2001)J/A+A/379/136 : UBVRI photometry of 3 young open clusters (Carraro+, 2001)J/A+A/429/607 : BV photometry of Berkeley 36, 73 and 34 (Ortolani+, 2005)J/MNRAS/299/834 : Berkeley 21 BVI photometry (Tosi+, 1998)J/MNRAS/346/18 : VIc photometry in Saurer A, B and C (Carraro+, 2003)J/MNRAS/349/641 : VIc, CT1 magnitudes in Trumpler 5 (Piatti+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/442/917https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/442/917http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/442/917https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/442/917https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/442/917http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/442/917GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/442/917/table1 (Photometry of Berkeley 73)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/442/917/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/442/917/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/442/917/table1?GETtext/xml+votable180.050000true95.509-6.29245830.005555555555555556Cone search capability for table J/A+A/442/917/table2 (Photometry of Berkeley 75)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/442/917/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/442/917/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/442/917/table2?GETtext/xml+votable180.050000true102.2322083-24.00056670.005555555555555556Cone search capability for table J/A+A/442/917/table3 (Photometry of Berkeley 25)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/442/917/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/442/917/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/442/917/table3?GETtext/xml+votable180.050000true100.2725-16.50063330.0055555555555555566/20763 20939 21372https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/442/917?format=asciiOpticalInfrareddefaultJ/A+A/442/917/table1Photometry of Berkeley 73recnoRecord number assigned by the VizieR team.
