We process the Sloan Digital Sky Survey (SDSS) images in ugriz passbands and construct corresponding mosaic images, taking special care of subtracting the varying sky background. We apply the galactic model developed in Tempel et al. (2010A&A...509A..91T) and far-infrared imaging to correct the photometry for intrinsic dust effects. We obtain observed and dust-corrected distributions of the surface brightness of M31 and a map of line-of-sight extinctions inside the galaxy. Our extinction model suggests that either M31 is intrinsically non-symmetric along the minor axis or the dust properties differ from those of the Milky Way. Assuming the latter case, we present the surface brightness distributions and integral photometry for the Sloan filters as well as the standard UBVRI system.2011A&A...526A.155Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/526/A155CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/526/A155https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/526/A155http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/526/A155https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/526/A155https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/526/A155http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/526/A155GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/526/A155/maps (List of FITS maps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/526/A155/maps?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/526/A155/maps?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/526/A155/maps?GETtext/xml+votable180.050000true7.736434.215820.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/526/A1556/2594https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/526/A155?format=asciidefaultJ/A+A/526/A155/mapsList of FITS mapsrecnoRecord number assigned by the VizieR team.
