Scale-free photometric planes showing the distribution of the real and simulated Type III S0s in the planes of (μ_0,i − μ_brkIII) and (μ_0,o − μ_brkIII) vs. h_i/R_brkIII (top panels), vs. h_o/R_brkIII (intermediate panels), and vs. R_brkIII/R₂₅ (bottom panels). 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.
