cds-question@unistra.fropen-star-clustersccd-photometryvisible-astronomybroad-band-photometryproper-motionsWe present reddening, photometric metallicity, age, and distance estimates for the Frolov 1 and NGC 7510 open clusters based on charge coupled device (CCD) UBV photometric and Gaia data. Photometric observations were collected using the 1m telescope of the TUBITAK National Observatory. Gaia data release 2 (DR2) proper motion data in the direction of two groupings were used to identify cluster membership. We determined mean proper motion values of (pmRAcosDE, pmDE) = (-3.02+/-0.10, -1.75+/-0.08) and (-3.66+/-0.07, -2.17+/-0.06)mas/yr for Frolov 1 and NGC 7510, respectively. We used two color diagrams to obtain E(B-V) color excesses for Frolov 1 and NGC 7510 of 0.65+/-0.06) and 1.05+/-0.05)mag, respectively. We derived the photometric metallicity of Frolov 1 as [Fe/H]=0.03+/-0.03) dex and adopted a solar metallicity for NGC 7510. Based on these reddening and metallicities, we determined the distance moduli and ages of the clusters by fitting stellar tracks and isochrones with the Padova and TRieste Stellar Evolution Code (PARSEC) isochrones to the cluster color-magnitude diagrams. Isochrone fitting distances for Frolov 1 and NGC 7510 are 2864+/-254 and 2818+/-247pc, respectively, which correspond to the ages 35+/-10Myr and 18+/-6Myr. We also calculated mean Gaia distances and compared them with those given in the literature and in this study, concluding that our results are in good agreement with previous work. Finally, we calculated the mass function slopes and found them to be X=-1.21+/-0.18 for Frolov 1 and X=-1.42+/-0.27 for NGC 7510.2021AN....342..538Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/342/538CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/342/538https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/342/538http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/342/538https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/342/538https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/342/538http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/342/538GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/342/538/table1 (Photometric and astrometric catalogue Frolov 1)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/342/538/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/342/538/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/342/538/table1?GETtext/xml+votable180.050000true358.992333361.79502220.005555555555555556Cone search capability for table J/AN/342/538/table2 (Photometric and astrometric catalogue NGC 7510)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/342/538/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/342/538/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/342/538/table2?GETtext/xml+votable180.050000true347.388416760.57658610.0055555555555555566/14295 14301 143101.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/342/538?format=asciiOpticaldefaultJ/AN/342/538/table1Photometric and astrometric catalogue Frolov 1e_Vmag? rms uncertainty on Vmagmagstat.error;phot.magfloatnullableU-B?
