cds-question@unistra.frgalaxy-clustersgalaxiesphotometryccd-photometryWe present an automatic procedure to perform reliable photometry of galaxies on SDSS images. We selected a sample of 5853 galaxies in the Coma and Virgo superclusters. For each galaxy, we derive Petrosian g and i magnitudes, surface brightness and color profiles. Unlike the SDSS pipeline, our procedure is not affected by the well known shredding problem and efficiently extracts Petrosian magnitudes for all galaxies. Hence we derived magnitudes even from the population of galaxies missed by the SDSS which represents ~25% of all Local supercluster galaxies and 95% of galaxies with g<11mag. After correcting the g and i magnitudes for Galactic and internal extinction, the blue and red sequences in the color magnitude diagram are well separated, with similar slopes. In addition, we study (i) the color-magnitude diagrams in different galaxy regions, the inner (r<=1kpc), intermediate (0.2R_{Pet}_>=r>=0.3R_{Pet}_) and outer, disk-dominated (r>=0.35R_{Pet}_)) zone, and (ii), we compute template color profiles, discussing the dependences of the templates on the galaxy masses and on their morphological type. The two analyses consistently lead to a picture where elliptical galaxies show no color gradients, irrespective of their masses. Spirals, instead, display a steeper gradient in their color profiles with increasing mass, which is consistent with the growing relevance of a bulge and/or a bar component above 10^10^M_{sun}_.2016A&A...591A..38Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/591/A38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/591/A38https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/591/A38http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/591/A38https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/591/A38https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/591/A38http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/591/A38GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/591/A38/table1 (Names, positions, magnitudes colors and masses (Zibetti et al., 2009MNRAS.400.1181Z))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/591/A38/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/591/A38/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/591/A38/table1?GETtext/xml+votable180.050000true150.068524.813980.0055555555555555564/648-649 1646 1732-1733 1735 1744 1746 1754 1759 1776-1777 1780 5/1286-1287 1289 1292 1296-1297 2167 2231 2234 2236-2237 2245 2247 2249-2250 2272 2274 2562 2565 2567 2570 2572-2573 2600 2602-2604 2688 6575 6578-6579 6582 6590-6591 6634 6917 6937 6939 6964-6965 6975 6997 6999 7005 7008-7009 7011 7013-7015 7022 7024 7029 7031-7033 7062-7063 7068-7069 7093-7095 7098-7099 7113-7115 7118-7119 7124-7126 7128-7130 7136-7137 7141 7148 7152 6/4479 4565-4566 5139-5140 5142 5161-5162 5164-5165 5172-5173 5175-5177 5179 5192-5193 5196 5200 5248 5250 5254-5255 5257 5260 5264 8234-8236 8243 8256 8282 8287 8320 8327 8330 8354-8355 8359-8360 8382 8416 8458-8460 8485 8492 8494 8655 8659 8662 8665-8667 8675 8677 8679 8683 8688-8689 8693-8694 8696 8698-8699 8721 8723 8831 8895 8917-8922 8932 8935 8940 8942-8943 8953-8954 8975 8985 8987 9005-9006 9009 9011-9012 9014-9015 9017-9018 9020 9024 9026 9028-9029 9034 9036 9092 9094-9095 9100 9104 9120 9354 10242 10252 10259 10265-10267 10272-10274 10278-10279 10284-10286 10296-10298 10302 10304-10305 10308-10310 10312-10314 10320 10336 10404-10406 10420 10432 10434 10440 10756 10760 26068-26069 26076 26083 26088 26090-26091 26093 26214 26217 26222-26223 26234 26261-26263 26265 26267-26268 26271 26285 26293-26295 26297 26306-26307 26309 26320 26322-26323 26332 26353-26354 26357 26412 26423 26432 26451 26466 26472 26502 26517-26518 26523 26528 26541-26542 26544 26554-26555 26592 26622 27087 27098 27123 27129-27130 27132 27135 27477 27485 27652-27654 27661 27676-27677 27679 27697 27745 27747 27753 27755 27789 27802 27811 27814 27820 27823 27828 27830 27838 27841 27845 27853 27855 27865-27866 27868-27869 27871 27878 27884 27894 27899 27921-27922 27924 27926 27929 27931 27934 27954-27955 27960 27965-27967 27981 27983 27986 27993 27995 28002 28005 28007 28010 28012 28014-28015 28017-28018 28024-28026 28030-28031 28040-28041 28043 28048-28050 28080-28082 28084-28085 28087 28092 28094-28095 28100-28102 28105 28107-28108 28110 28112-28113 28115 28122-28123 28137-28139 28141-28143 28162 28167-28168 28170 28172-28173 28178 28184 28200-28201 28208 28225 28237-28239 28241-28244 28246-28247 28260 28263 28269 28280-28281 28283-28286 28367 28369 28371 28388-28389 28401-28406 28408-28410 28412 28449-28451 28464 28466-28467 28470-28471 28508-28510 28525-28530 28552 28554-28558 28560-28561 28563 28568-28569 28572-28574 28576 28581 28612 28616 31423 31469 31475https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/591/A38?format=asciiOpticaldefaultJ/A+A/591/A38/table1Names, positions, magnitudes colors and masses (Zibetti et al., 2009MNRAS.400.1181Z)SDSSSDSS identification (JHHMMSS.s+DDMMSS)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
