Baryonic mass fraction within R_eff for CSWA 31 compared to galaxy, group, and cluster scales in the literature (samples combined by Newman et al. 2015). The of CSWA 31 at R_eff = 27.2 kpc inferred from model Img-MP (L&D) (red square) is comparable to massive ellipticals in the center of cluster-scale lenses, but much smaller than for BGGs. Nevertheless, the obtained using the stellar mass from SED fitting (green square) is closer to group-scale lenses.
