Scale-free photometric planes showing the distributions of h_i/h_o vs. R_brkIII and R_brkIII/R₂₅ of our Type III S0-like remnants, compared to real antitruncated S0s (E08; G11). Data of the antitruncations formed in the minor merger simulations by Y07 are overplotted for comparison in the left diagram. Dotted line: expected relations derived from the simple observational scaling relations h_i ∝ R_brkIII, h_o ∝ R_brkIII, and μ_brkIII ∝ R_brkIII (see Sect. 3.6). Consult the legend in the figure.
