cds-question@unistra.frgalaxy-clustersabsolute-magnitudegalaxiesphotometryWe have derived detailed R-band luminosity profiles and structural parameters for a total of 430 brightest cluster galaxies (BCGs), down to a limiting surface brightness of 24.5mag/arcsec^2^. Light profiles were initially fitted with a Sersic's R^1/n^ model, but we found that 205 (~48%) BCGs require a double component model to accurately match their light profiles. The best fit for these 205 galaxies is an inner Sersic model, with indices n~1-7, plus an outer exponential component. Thus, we establish the existence of two categories of the BCG luminosity profiles: single and double component profiles. We found that double profile BCGs are brighter (~0.2mag) than single profile BCGs. From a subsample of 24 BCGs, we found strong evidence that extra-light at intermediate radii in double profile BCGs is related to the presence of a faint stellar envelope. Similarly, from another subsample of 12 BCGs we also found that extra-light is related to star formation.2011ApJS..195...15Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/195/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/165 : Measured Redshifts of Abell Clusters of Galaxies (Andernach 1991)VII/87 : Data on 1889 Abell's clusters of galaxies (Leir+ 1977)J/AJ/125/478 : HST imaging of brightest cluster galaxies (Laine+, 2003)J/ApJ/440/28 : Brightest Cluster Galaxies velocities (Postman+ 1995)J/ApJ/425/418 : Absoulue R mag of brightest clusters galaxies (Lauer+, 1994)J/ApJ/241/486 : Absolute magnitudes in 116 nearby Abell clusters (Hoessel+,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/195/15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/195/15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/195/15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/195/15https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/195/15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/195/15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/195/15/table2 (BCGs photometrical parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/195/15/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/195/15/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/195/15/table2?GETtext/xml+votable180.050000true3.80417-23.888330.0055555555555555566/206 207 242 462 529 659 663 675 1006 1023 2172 2278 2286 2389 2409 2432 3953 4185 4341 4438 4990 5005 5030 5046 5363 5373 5394 5395 5438 5524 5535 5616 5827 5929 5967 5975 5982 6000 6223 6335 6434 6535 6741 6892 6951 6992 7026 7187 7354 7515 7589 7733 7883 8220 8245 8247 8258 8264 8266 8271 8442 8515 8520 8648 8735 8759 8788 8856 8859 8884 8923 8958 9021 9036 9116 9170 9368 9468 9471 9531 9757 9992 10115 10271 10311 10312 10318 10410 10483 10716 10823 11003 11182 11239 11241 11775 11809 11992 12114 12118 12121 12153 15112 15290 16098 16297 16410 16434 16492 16541 16543 16582 16584 16599 16610 16642 16676 16677 16693 16695 16696 16697 16713 16758 16765 16781 16782 16854 16926 16945 17061 17080 17136 17237 17298 17300 17387 17571 17662 17673 17801 17805 17810 17840 17841 17993 18009 18016 18028 18035 18113 18168 18176 18184 18205 18272 18324 18365 18389 18410 18415 18437 18450 18515 18548 18607 18622 18778 18953 19140 19204 19314 19362 19501 19608 19656 19777 19782 19783 19797 19798 19912 19993 20021 20035 20072 20082 20083 20094 20112 20282 20308 20355 20361 20481 20511 20642 20658 20706 20716 20734 21039 21064 21073 21156 21766 22374 22577 22615 23027 23406 24622 24637 24848 24912 24943 25042 25410 25474 25485 25669 26042 26043 26109 26329 26432 26734 26770 26783 26815 26848 26854 26903 26906 26944 26987 27060 27083 27174 27175 27224 27238 27407 27417 27472 27486 27586 27595 27685 27775 27867 27886 27962 27966 28249 28293 28345 28360 28383 28414 28415 28571 33224 33227 33235 33264 33346 33427 33466 33605 33624 33628 33648 33649 33656 33657 33658 33730 33731 33750 33756 33774 34111 34155 34171 34229 34307 34371 34436 34440 34442 34443 34461 34463 34468 34480 34490 34518 34546 34553 34703 34746 34805 34955 34961 35040 35045 35048 35052 35055 35091 35097 35343 35392 35530 35595 35618 35645 35858 35962 35976 36048 36062 36098 36263 36364 36534 36573 36639 36661 37550 39068 39077 39079 39137 39140 39459 39613 40214 40233 40777 40988 43451 43803 43806 43809 43823 43830 43835 43837 43843 43848 43849 43876 43914 43915 43920 43931 43939 43950 43968 43977 44210 44554 44958 45219 45371 45476 45502 45542 45562 45566 45685 45859 45893 45915 45941 45942 45981 45984 46043 46077 46223 46244 46253 46255 46258 46280 46456 46471 46575 46652 46738 46754 46756 46866 46868 46891 46911 47030 47188 47543 47583 48134 48193 48319 48323 48344 48439 48447 48459 48483 48594 48613 48615 49091https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/195/15?format=asciiOpticaldefaultJ/ApJS/195/15/table2BCGs photometrical parametersrecnoRecord number assigned by the VizieR team.
