cds-question@unistra.fropen-star-clustersvilnius-photometryWe present the results of eight-color CCD photometry of 674 stars in the direction of the open cluster Tombaugh 5 in Camelopardalis. The stars are observed in the Vilnius system supplemented by the broad-band I filter; the field is of 22' diameter, the limiting magnitude is V=17.7mag. The catalog contains the coordinates, V magnitudes, seven color indices, two-dimensional spectral types determined from photometric parameters, interstellar extinctions and distances. The color-magnitude diagram plotted for 480 individually dereddened stars is used to identify cluster members and to determine the distance (1.74kpc) and age (200-250Myr) of the cluster. The fain test cluster stars classified are of spectral class G0. The cluster contains two blue stragglers of spectral classes B2-B4, both of them seem to be visual binaries. The extinction AV for the cluster stars is non-uniform, being spread between 2 and 3mag, with a mean value of 2.42mag. The extinction vs. distance dependence can be modeled by the Parenago exponential curve with two dust concentrations in the Camelopardalis dark clouds at about 150pc and the Cam OB1 association clouds at 0.9-1.0kpc.2011BaltA..20....1Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/BaltA/20/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/BaltA/20/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/BaltA/20/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/BaltA/20/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/BaltA/20/1https://vizier.iucaa.in/viz-bin/votable?-source=J/BaltA/20/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/BaltA/20/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/BaltA/20/1/table3 (Photometry, spectral and luminosity classes, interstellar extinctions, distances and cluster membership for stars in the Tombough 5 area)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/BaltA/20/1/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/BaltA/20/1/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/BaltA/20/1/table3?GETtext/xml+votable180.050000true56.6262559.0972220.0055555555555555566/33623.561607812030676e-19 3.741500294832266e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/BaltA/20/1?format=asciiOpticaldefaultJ/BaltA/20/1/table3Photometry, spectral and luminosity classes, interstellar extinctions, distances and cluster membership for stars in the Tombough 5 areaSeq[1/674] Sequential numbermeta.recordintprimaryn_Seq[*] * indicates a note in notes.dat filemeta.notecharRAJ2000Right ascension (J2000)pos.eq.ra;meta.mainDEJ2000Declination (J2000)pos.eq.dec;meta.mainVmag[8.8/17.8] Vilnius V magnitudemagphot.mag;em.opt.Vfloatu_Vmag[: ] Uncertainty flag on Vmagmeta.code.errorcharU-V?
