cds-question@unistra.frgalaxiescatalogsapparent-magnitudeA two-color study of the galaxies detected on POSS-I in a 289deg^2^ region centered on the North Galactic Pole is presented. We use a variety of mapping techniques to characterize the large-scale spatial distribution of galaxies. The depth and sample size of this new survey allows, for the first time, the isolation of large photometric subsamples of galaxies in high- and low-density environments on the scale of superclusters. Our principal finding is a statistically significant difference between the mean photometric properties of these subsamples in the sense that galaxies in the high-density Coma and filament environments have redded colors and larger concentration indices than galaxies drawn from low-density interfilament regions. These results are in agreement with the known morphology-density relation.1995AJ....110.2009Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/VII/204CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VII/204https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VII/204http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VII/204https://vizier.cds.unistra.fr/viz-bin/votable?-source=VII/204https://vizier.iucaa.in/viz-bin/votable?-source=VII/204http://vizieridia.saao.ac.za/viz-bin/votable?-source=VII/204GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table VII/204/catalog (All APS-measured galaxies with Omag <= 20.0 (NGP9))https://vizier.cds.unistra.fr/viz-bin/conesearch/VII/204/catalog?https://vizier.iucaa.in/viz-bin/conesearch/VII/204/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/VII/204/catalog?GETtext/xml+votable180.050000true187.118215138.10731950.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/VII/204?format=asciiOpticaldefaultVII/204/catalogAll APS-measured galaxies with Omag <= 20.0 (NGP9)recnoRecord number assigned by the VizieR team.
