Distribution of C_i in the Λ − ε plane, where Λ and ε are measured at the location of maximum rotational support for the entire sample of simulated ETGs. Galaxies are divided in low-mass FRs (left), high-mass FRs (center), and SRs (right). The first row of panels shows the median μ(C_i) in each bin. The second row shows the root-mean-square scatter around the mean, σ(C_i). The third row shows the ratio between scatter and median. The location of the ePN.S galaxies in the Λ_light − ε plane is also shown with open circles. For each ePN.S ETG, the median C_i value of its “analogs”, selected to have similar Λ, ε, and M_*, is used to “de-project” j_p (see Sect. 8).
