cds-question@unistra.frgalaxy-clustersapparent-magnitudeWe have derived the galaxy luminosity function (GLF) in the cluster of galaxies Abell 496 from a wide field image in the I band. A single Schechter function reproduces quite well the GLF in the 17<=I_AB_<=22 (-19.5<=M_I_<=eq-14.5) magnitude interval, and the power law index of this function is found to be somewhat steeper in the outer regions than in the inner regions. This result agrees with the idea that faint galaxies are more abundant in the outer regions of clusters, while in the denser inner regions they have partly been accreted by larger galaxies or have been dimmed or even disrupted by tidal interactions.2002A&A...393..439Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/393/439CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/139/525 : Abell 496 heliocentric velocities (Durret+, 1999)J/A+AS/139/559 : Abell 496 photometric catalogue (Slezak+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/393/439https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/393/439http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/393/439https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/393/439https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/393/439http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/393/439GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/393/439/catalog (Catalogue of galaxies in the direction of the cluster Abell 496)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/393/439/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/393/439/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/393/439/catalog?GETtext/xml+votable180.050000true68.0500136-13.4566190.0055555555555555566/22555 22577 22580https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/393/439?format=asciiOpticaldefaultJ/A+A/393/439/catalogCatalogue of galaxies in the direction of the cluster Abell 496recnoRecord number assigned by the VizieR team.
