cds-question@unistra.frgalaxiescatalogsphotometryredshiftedWe present the construction and describe the properties of the Padova-Millennium Galaxy and Group Catalogue (PM2GC), a galaxy catalogue representative of the general field population in the local Universe. We characterize galaxy environments by identifying galaxy groups at 0.04<=z<=0.1 with a Friends-of-Friends (FoF) algorithm using a complete sample of 3210 galaxies brighter than M_B_=-18.7 taken from the Millennium Galaxy Catalogue (MGC, Liske et al., 2003, Cat. VII/240), a 38deg^2^ image photometric and spectroscopic equatorial survey. We identified 176 groups with at least three members, comprising in total 1057 galaxies and representing ~43 per cent of the general field population in that redshift range.2011MNRAS.416..727Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/416/727CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/240 : Millennium Galaxy Catalogue (Liske+, 2003)J/ApJS/167/1 : Galaxy groups and clusters from SDSS (Berlind+, 2006)J/A+A/474/783 : Main galaxy groups from SDSS-DR5 (Deng+, 2007)J/A+A/479/927 : Group of galaxies in SDSS 5 (Tago+, 2008)J/MNRAS/348/866 : Galaxy groups in the 2dFGRS (Eke+, 2004)J/MNRAS/395/255 : Compact groups of galaxies in SDSS DR6 (McConnachie+, 2009)J/A+A/514/A102 : SDSS DR7 groups of galaxies (Tago+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/416/727https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/416/727http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/416/727https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/416/727https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/416/727http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/416/727GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/416/727/table2 (Galaxy groups with their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/727/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/727/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/727/table2?GETtext/xml+votable180.050000true170.3258-0.20970.005555555555555556Cone search capability for table J/MNRAS/416/727/table3 (Galaxies in groups with their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/727/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/727/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/727/table3?GETtext/xml+votable180.050000true150.10510.23960.005555555555555556Cone search capability for table J/MNRAS/416/727/table6 (Galaxies in general field catalogue with their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/727/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/727/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/727/table6?GETtext/xml+votable180.050000true215.9539-0.24830.0055555555555555565/6489-6490 6501 6505-6506 6549-6550 6553-6554 6565-6566 6569-6570 6741-6742 6745-6746 6757-6758 6761-6762 6805-6806 6809 6/25599 25855 25919 25935 25944-25946 25955 25964 25968 25999 26003 26008-26010 26012 26019 26028 26048 26175 26191 26195 26204 26211 26220 26224 26255 26259 26268 26275 26284 26288 26304 26368 26879 26943 26959 26963 26972 26979 26988 26992 27023 27027 27036 27043 27052 27056 27072 27215 27219 27228 27248 27392 27648https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/416/727?format=asciiOpticaldefaultJ/MNRAS/416/727/table2Galaxy groups with their propertiesrecnoRecord number assigned by the VizieR team.
