In this context, blobs may correspond to stars born in-situ versus those accreted from satellites, and the task of blob detection is to disentangle these components.

Overall, we find significant differences in the distributions of quantities derived from S\'ersic profiles ($g'-r'$, $r'-i'$, $R_e$, and $\bar{\mu}_{e, r'}$), and non-parametric indices ($A$ and $S$) between the Fornax main cluster and Fornax A group.

We do not see any change in the shape of RCs with respect to the local star-forming disk-type galaxies.
