Comparison of λ_Re versus ellipticity ϵ_Re for the M3G sample and galaxies drawn from several reference surveys. The M3G galaxies are shown as large red (BCGs) and blue (non-BCGs) circles, with uncertainties smaller than the symbols. Small satellites of M3G galaxies found in the MUSE FoV are represented as teal circles, while small light green circles are for ATLAS^3D galaxies. Triangles are used for galaxies from the MASSIVE survey, where filled (brown) triangles are their BGGs, taken from Veale et al. (2017b). Dark red hexagons are BGGs from Loubser et al. (2022). A solid dark green line separates fast rotators from slow rotators, as $0.31\times \sqrt{{ϵ}_{\mathrm{Re}}}$ (Emsellem et al. 2011), while the solid grey line, given by Cappellari (2016) as 0.08 + ϵ/4, is an alternative separatrix. The dashed magenta line shows the edge-on view for ellipsoidal galaxies integrated up to infinity with β = 0.7 × ϵ (Cappellari et al. 2007). The dotted black lines show the location of galaxies, originally on the magenta line, as the inclination is varied by 10°, while the dashed black lines trace locations for galaxies with intrinsic ellipticities from 0.25 (lowest) to 0.85 (highest) in step of 0.1.
