cds-question@unistra.frgalaxy-clustersgalaxy-kinematicsvisible-astronomyWe explore several ways to dissect brightest cluster galaxies (BCGs) and their surrounding intracluster light (ICL) using a surface brightness (SB) cut, a luminosity cut, excess light above a de Vaucouleurs profile, or a double Sersic decomposition. Assuming that all light above M{<}-21.85g'mag is attributable to the ICL, we find that an average fraction of f_ICL_^MT^=71+/-22% of all diffuse light centered on the BCG belongs to the ICL. Likewise, if we assume that all light fainter than SB>27g'mag/arcsec^2^ belongs to the ICL, the average ICL fraction is f_ICL_^SB27^=34+/-19% . After fitting a de Vaucouleurs profile to the inner parts of the SB profile, we detect excess light at large radii, corresponding to an average ICL fraction of f_ICL_^DV^=48+/-20% . Finally, by decomposing the SB profile into two Sersic functions, we find an average ICL fraction of f_ICL_^Sx^=52+/-21% associated with the outer Sersic component. Our measured ICL and BCG+ICL luminosities agree well with predictions from high-resolution simulations where the outer Sersic component traces the unrelaxed, accreted stellar material. BCG and ICL properties defined in this way are correlated with cluster parameters to study the coevolution of BCGs, ICL, and their host clusters. We find positive correlations between BCG+ICL brightness and cluster mass, cluster velocity dispersion, cluster radius, and integrated satellite brightness, confirming that BCG/ICL growth is indeed coupled with cluster growth. On average, the ICL is better aligned than the BCG with the host cluster in terms of position angle, ellipticity, and centering. That makes it a potential dark-matter tracer.2021ApJS..252...27Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/252/27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)VII/110 : Rich Clusters of Galaxies (Abell+ 1989)J/ApJ/664/226 : Nuker law parameters of early-type galaxies (Lauer+, 2007)J/MNRAS/379/867 : BCG C4 cluster catalog (von der Linden+, 2007)J/ApJS/182/216 : Surface photometry of Virgo ellipticals (Kormendy+, 2009)J/ApJS/195/15 : Luminosity profiles of BCGs (Donzelli+, 2011)J/ApJ/797/82 : Brightest cluster galaxies in Abell clusters (Lauer+, 2014)J/A+A/609/A78 : MUSE combined data cubes for NGC 3311 (Barbosa+, 2018)J/ApJS/247/43 : WWFI g'-band obs. of bright cluster galaxies (Kluge+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/252/27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/252/27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/252/27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/252/27https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/252/27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/252/27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/252/27/table2 (Host cluster parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/252/27/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/252/27/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/252/27/table2?GETtext/xml+votable180.050000true10.06716.87950.0055555555555555566/50 206 242 659 675 986 1006 1701 2172 2278 2286 2388 2409 2432 3953 4339 4341 4519 4675 5005 5030 5046 5394-5395 5399 5411 5438 5524 5545 5616 5774 5929 5964 5967 5975 6009 6223 6247 6335 6434 6535 6741 6892 6951 6992 7187 7354 7515 7589 7733 7861 8220 8264 8271 8442 8515 8520 8526 8648 8735 8759 8856 8859 9021 9036 9072 9116 9287 9368 9468 9471 9776 10182 10271 10311-10312 10318 10379 10410 10483 10627 10716 10823 11003 11182 11241 11250 11591 11809 12114 12118 12121 12153 13380 15112 15290 16098 17237 18168 18205 18272 18324 18365 18367 18389 18410-18411 18415 19314 19325 19362 19408 19432 19501 19608 19656 19760 19782-19783 19798 19968 19987 19993 20021 20035 20072 20082-20083 20094 20112 20114 20282 20355 20361 22374 23027 24238 26109 26432 27355 27417 27486 27586 27595 27652 27671 27685 27775 27803 27840 27886 27962 27966 28005 28249 28290 28345 28360 28414-28415 28430 28571 28622https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/252/27?format=asciiOpticaldefaultJ/ApJS/252/27/table2Host cluster parametersSimbadNameSimbad column added by the CDSmeta.idchare_Msat[0.4/4]?
