However, only half of the 1700 known galactic open clusters have been properly observed so far, making any statistical investigation insignificant, especially at larger distances from the Sun. We study marginally investigated or neglected open clusters with Bessell CCD BVR photometry, whose data were used to fit isochrones to the individual color-magnitude diagrams. We examined the galactic clusters Basel 11b, King 14 and Czernik 43, the last being observed for the first time to this extent. As well as a careful comparison to available photometry, their parameters such as age, interstellar reddening, distance and apparent diameter were determined. The obtained cluster properties were verified by near infrared 2MASS data. The three investigated intermediate age clusters are all located in the galactic disk with distances between 1.8 and 3.0kpc from the Sun.2006A&A...454..179Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/454/179CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/374/504 : UBVI photometry of NGC 7654 (Pandey+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/454/179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/454/179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/454/179https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/454/179https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/454/179http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/454/179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/454/179/table1 (Observed program stars of Basel 11b)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/454/179/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/454/179/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/454/179/table1?GETtext/xml+votable180.050000true89.5858047221.965806940.005555555555555556Cone search capability for table J/A+A/454/179/table2 (Observed program stars of King 14)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/454/179/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/454/179/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/454/179/table2?GETtext/xml+votable180.050000true8.106489263.17576560.005555555555555556Cone search capability for table J/A+A/454/179/table3 (Observed program stars of Czernik 43)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/454/179/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/454/179/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/454/179/table3?GETtext/xml+votable180.050000true351.5098180661.382524440.0055555555555555566/3060 14320 24329https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/454/179?format=asciiOpticalInfrareddefaultJ/A+A/454/179/table1Observed program stars of Basel 11brecnoRecord number assigned by the VizieR team.
