Using mainly spectroscopic redshifts, we find 132 members from our sample of 219 galaxies. In our sample of 132 members, we find 51 non-dwarfs and 81 dwarfs, and amongst our 32 non- members, we find 4 dwarfs and 28 non-dwarfs. We do not have redshifts for the remaining 55 galaxies. We present bulge-disc decomposition of the sample using galfit and obtain parameters for our sample. Using visual inspection of residuals, we do a morphological classification of the galaxies. We studied the relation of morphological types with Bulge to Total Light Ratio (B/T), colour-magnitude relation (CMR), Sersic index (n), Kormendy relation, and cross- correlations between these parameters for the bulges and galaxies. This work helps us understand important relations between various parameters like B/T, colour, and n as well as insights into the merger history of these galaxies in terms of their positions in the Kormendy Diagram and their Sersic indices. We find that there are significantly more E/SO, SOs galaxies in the member population compared to non-members.2022MNRAS.510.4463Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/4463CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/191/143 : HST/ACS Coma cluster survey.
