We have undertaken an investigation of several distant clusters (Berkeley 19, Berkeley 44, King 25, NGC 6802, NGC 6827, Berkeley 52, Berkeley 56, NGC 7142, NGC 7245, and King 9) to develop procedures for separating probable cluster members from the background field. We next created a simple quantitative approach for finding approximate cluster distances, reddenings, and ages. We first conclude that with the possible exception of King 25 they are probably all physical clusters.2011AJ....141...92Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/92https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/92http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/92https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/92https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/92http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/92GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/141/92/table1 (Summary information for the target clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/92/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/92/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/92/table1?GETtext/xml+votable180.050000true81.013833329.568750.005555555555555556Cone search capability for table J/AJ/141/92/table9 (Photometric catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/92/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/92/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/92/table9?GETtext/xml+votable180.050000true80.880943129.65865030.0055555555555555566/12978 12984 13054 13055 13887 13930 13973 13988 13989 13991 14016 14243 14246 14249 14252 14336 24483 24489 30692 320893.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/141/92?format=asciiOpticalInfrareddefaultJ/AJ/141/92/table1Summary information for the target clustersrecnoRecord number assigned by the VizieR team.
