cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryWe have obtained CCD UBVI_KC_ photometry down to V~21.0 for the open clusters Berkeley 26, Czernik 27, Melotte 72, NGC 2479 and BH 37. The latter has never been studied before. Cluster stellar density profiles were obtained from star counts in appropriate-sized boxes distributed throughout the entire observed fields. Based on different measured indices, we estimate the ages of Berkeley 26, Melotte 72 and NGC 2479. On the other hand, we indicate possible solutions for the cluster fundamental parameters by matching theoretical isochrones which reasonably reproduce the main cluster features in their colour-magnitude diagrams. In the case of NGC 2479, the cluster E(BV) and E(VI) colour excesses and apparent distance modulus were estimated from the fit of the zero-age main sequence to the colour-colour and colour-magnitude diagrams, respectively.2010MNRAS.402.2720Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/402/2720CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/107/39 : IC 2714 UBV photometry (Claria+ 1994)J/A+AS/127/423 : VI photometry of Westerlund 1 and 2 (Piatti+ 1998)J/A+AS/128/131 : UBV photometry of NGC 2323 (Claria+ 1998)J/ApJS/116/263 : VI photometry of open clusters (Piatti+ 1998)J/A+A/360/529 : BVI photometry of 4 young open clusters (Piatti+, 2000)J/A+A/370/931 : BVI photometry of 4 open clusters (Piatti+, 2001)J/A+A/379/453 : BVI photometry of 5 open cluster candidates (Piatti+, 2001)J/A+A/388/179 : BVI photometry of two open clusters (Piatti+, 2002)J/A+A/399/543 : Photometry and Coravel obs. of IC 2488 (Claria+, 2003)J/A+A/409/541 : UBV photometry of IC 2395 (Claria+, 2003)J/MNRAS/340/1249 : VIc magnitudes in NGC 2194 (Piatti+, 2003)J/MNRAS/346/390 : VI and CMT1 photometry of NGC 2627 (Piatti+, 2003)J/MNRAS/349/641 : VIc, CT1 magnitudes in Trumpler 5 (Piatti+, 2004)J/A+A/418/979 : VI and CT1 photometry in NGC 2324 field (Piatti+, 2004)J/A+A/421/991 : CT1 photometry in Tombaugh 1 (Piatti+, 2004)J/PASP/117/22 : NGC 6318 CCD BVI photometry (Piatti+, 2005)J/other/NewA/11.262 : BVIc photometry in Lynga 11 (Piatti+, 2006)J/MNRAS/367/599 : BVI photometry of NGC 5288 (Piatti+, 2006)J/MNRAS/377/1737 : BVI photometry of NGC 2489 (Piatti+, 2007)J/MNRAS/397/1073 : UBVI photometry in NGC 2587 (Piatti+, 2009)J/PASP/122/288 : UBVI_KC_ photometry in NGC 2309 (Piatti+, 2010)J/MNRAS/408/1147 : 4 Galactic open clusters UBVI photometry (Piatti+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/402/2720https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/402/2720http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/402/2720https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/402/2720https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/402/2720http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/402/2720GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/402/2720/table1 (Basic parameters of the five clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2720/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2720/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2720/table1?GETtext/xml+votable180.050000true102.5755.750.005555555555555556Cone search capability for table J/MNRAS/402/2720/table3 (CCD VI data of stars in the field of Berkeley 26)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2720/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2720/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2720/table3?GETtext/xml+votable180.050000true102.49163065.87270720.005555555555555556Cone search capability for table J/MNRAS/402/2720/table4 (CCD BVI data of stars in the field of Czernik 27)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2720/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2720/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2720/table4?GETtext/xml+votable180.050000true105.78058786.52439330.005555555555555556Cone search capability for table J/MNRAS/402/2720/table5 (CCD BVI data of stars in the field of Melotte 72)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2720/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2720/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2720/table5?GETtext/xml+votable180.050000true114.7107569-10.56546690.005555555555555556Cone search capability for table J/MNRAS/402/2720/table6 (CCD UBVI data of stars in the field of NGC 2479)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2720/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2720/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2720/table6?GETtext/xml+votable180.050000true118.7059797-17.71102310.005555555555555556Cone search capability for table J/MNRAS/402/2720/table7 (CCD BVI data of stars in the field of BH 37)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2720/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2720/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2720/table7?GETtext/xml+votable180.050000true128.8880428-43.48617720.0055555555555555566/21602 22235 22257 22402 22408 39244 39246 40625 40627-40628 406303.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/402/2720?format=asciiOpticalInfrareddefaultJ/MNRAS/402/2720/table1Basic parameters of the five clustersrecnoRecord number assigned by the VizieR team.
