We define our BCGs by simultaneous consideration of legacy X-ray data from ROSAT, maximum-likelihood outputs from an optical cluster-finder algorithm and visual inspection. Using SDSS imaging data, we fit Sersic profiles to our BCGs in three bands (g, r, i) with SIGMA a GALFIT-based software wrapper. We examine the reliability of our fits by running our pipeline on ~10^4^ point spread function-convolved model profiles injected into eight random cluster fields; we then use the results of this analysis to create a robust subsample of 198 BCGs. We outline three cluster properties of interest: overall cluster X-ray luminosity (L_X_), cluster richness as estimated by REDMAPPER ({lambda}),and cluster halo mass (M_200_), which is estimated via velocity dispersion. In general, there are significant correlations with BCG stellar mass between all three environmental properties, but no significant trends arise with either Sersic index or effective radius. There is no major environmental dependence on the strength of the relation between effective radius and BCG stellar mass. Stellar mass therefore arises as the most important factor governing BCG morphology. Our results indicate that our sample consists of a large number of relaxed, mature clusters containing broadly homogeneous BCGs up to z~0.3, suggesting that there is little evidence for much ongoing structural evolution for BCGs in these systems.2018MNRAS.478.4952Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/478/4952CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/636/A97 : SDSS-IV/SPIDERS X-ray PS Spectroscopic Catalog (Comparat+ 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/478/4952https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/478/4952http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/478/4952https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/478/4952https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/478/4952http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/478/4952GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/478/4952/tablec1 (Parameters used in this study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/478/4952/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/478/4952/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/478/4952/tablec1?GETtext/xml+votable180.050000true139.802554.857080.0055555555555555566/675 690 696 2058 2061 2082 2102 2109 2144 2179 2185 5099 5113 5116 5119 5340 5352 5358 5400 5405 5438 5451 5454-5455 5458 5461 5468 5475 5481 5524 5535 5551 5562 5567 5590 5603 5606 5608 5618 5622 5625 5660 5697 5699 5701 5715 5726 5743 5756 5758 5762 5764 5766 5769 5776 5780 5824-5825 5846 5865 5873 5879 5881 5894 5900 5921 5923 5929 5931 5936 5974 5982 5988 5991 5996 6005 6017 6019 6022 6028-6029 6039 6045 6071 6077 6079 6086 6088 6092 6430-6431 6449 6473 6490 6495 6522 6551 6553 6584 6601-6603 6608-6609 6613-6615 6620 6628 6641 6652 6655 7175 7187 7198 7203 7205 7223 7229 7263-7266 7269-7271 7277-7278 7301 7310 7317-7318 7329 7338 7345 7362 7372 7375-7376 7394 7433 7436 7448-7449 7464 10011 10033 10042 10636 10656-10657 10659-10661 10664 10679 10684 10689 10691 10700 10711 10717-10718 10724 10747 10771 10837-10838 10840-10842 10852 10854 10856 10871 10874 10899 10943 10947 10974 10976 10986 10994 11005 11013 11027 11035-11036 11040-11042 11045 11049 11058 11063 11068 11073 11076 11080 11096 11100 11136-11137 11141 11182 11195 11279 11287 11306 11315 11320 12621 12633 12638 12749 13362 13386 17374 17623 17626 17630 17684 17695 17701 17711-17712 17715 17718 17720 17724 17728 17732-17733 17742 17746 17787 17799 17802 17805 17808-17810 17816-17817 17841-17842 17867 17890 17978 17983 17993 18006 18008 18011 18016 18019 18021 18023 18026 18034 18040-18041 18049 18067 18074 18076 18079 18085 18110 18134 18176-18177 18779 19465 19467 19482 19495 19506 19774 19799 19816 19818 19857 19860 19905-19906 19909 19912 19925 19932 19935 19967 20027 20029 20067-20068 20077 20085-20086 20211 20234-20235 20310 28653 28661 36799 36846 36858https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/478/4952?format=asciiOpticaldefaultJ/MNRAS/478/4952/tablec1Parameters used in this studySimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
