cds-question@unistra.fropen-star-clustersvilnius-photometryWe have performed multicolor CCD observations of the central area of NGC 752 to search for faint, low-mass members of this open cluster. Four 12'x12' fields were taken on the 1.8m Vatican Advanced Technology Telescope (Mt. Graham, Arizona) using a 4K CCD camera and eight intermediate-band filters of the Stromvil (Stromgren + Vilnius) system. In this paper we present a catalog of photometry for 405 stars down to the limiting magnitude V=18.5, which contains V magnitudes and color indices of the Vilnius system, together with photometric determinations of spectral types, absolute magnitudes MV , interstellar reddening values E(Y-V) and metallicity parameters [Fe/H]. The good quality multicolor data made it possible to identify the locus of the lower main sequence to four magnitudes beyond the previous (photographic) limit. A relatively small number of photometric members identified at faint magnitudes seems to be indicative of actual dissolution of the cluster from the low-mass end.2011BaltA..20...27Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/BaltA/20/27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/177 : Proper motions in NGC 752 (Platais 1992)J/PASP/106/281 : Photometry and radial velocities in NGC752 (Daniel+, 1994)J/A+A/339/423 : Velocities of red giants in NGC 752 (Mermilliod+ 1998)J/A+A/490/113 : X-ray sources in NGC 752 (Giardino+, 2008)J/MNRAS/446/3562 : Red giants abundances in NGC752 (Bocek Topcu+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/BaltA/20/27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/BaltA/20/27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/BaltA/20/27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/BaltA/20/27https://vizier.iucaa.in/viz-bin/votable?-source=J/BaltA/20/27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/BaltA/20/27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/BaltA/20/27/stars (Vilnius photometry of stars in the area of NGC 752)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/BaltA/20/27/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/BaltA/20/27/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/BaltA/20/27/stars?GETtext/xml+votable180.050000true29.11541737.9022220.0055555555555555566/24363.561607812030676e-19 3.741500294832266e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/BaltA/20/27?format=asciiOpticaldefaultJ/BaltA/20/27/starsVilnius photometry of stars in the area of NGC 752Seq[1/405] Sequential numbermeta.recordintprimaryHein[1/396]?
