cds-question@unistra.frgalaxy-clustersapparent-magnitudeWe present and discuss optical measurements of the faint end of the galaxy luminosity function down to M_R_=-10 in five different local environments of varying galaxy density and morphological content. The environments we studied, in order of decreasing galaxy density, are the Virgo Cluster, the NGC 1407 Group, the Coma I Group, the Leo Group and the NGC 1023 Group. Our results come from a deep wide-angle survey with the National Astronomical Observatories of Japan Subaru 8-m Telescope on Mauna Kea and are sensitive down to very faint surface-brightness levels. Galaxies were identified as group or cluster members on the basis of their surface brightness and morphology. The faintest galaxies in our sample have R~22.5. There were thousands of fainter galaxies but we cannot distinguish cluster members from background galaxies at these faint limits so do not attempt to determine a luminosity function fainter than M_R_=-10.2002MNRAS.335..712Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/335/712CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/90/1681 : The Virgo Cluster Catalog (VCC) (Binggeli+, 1985)J/MNRAS/333/423 : Luminosity function of the Virgo Cluster (Trentham+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/335/712https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/335/712http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/335/712https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/335/712https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/335/712http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/335/712GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/335/712/tables (Tables 2 to 6 (Virgo, NGC 1407 Group, Coma I, Leo and NGC 1023 Group) samples)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/335/712/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/335/712/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/335/712/tables?GETtext/xml+votable180.050000true186.5487512.9461110.0055555555555555566/2369 2372 2374-2375 2380-2381 27515 27518 27604-27605 27607 27767 27772-27773 27938 28495 28504 28506 28516-28517 36247 36253 36290https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/335/712?format=asciiOpticaldefaultJ/MNRAS/335/712/tablesTables 2 to 6 (Virgo, NGC 1407 Group, Coma I, Leo and NGC 1023 Group) samplesrecnoRecord number assigned by the VizieR team.
