The baryonic mass fraction as a function of mass M₂₀₀ with the equivalent V₂₀₀ noted on the top axis. Data and symbols are the same as in Figures 2 and 3. The top panels follow from using rotation curve fits to estimate halo mass as in Figure 2 for pseudo-isothermal (top-left panel) and NFW (top-right panel) halo models. The bottom panels follow from using the flat rotation speed as the halo mass estimator as in Figure 3 with f_v = 1.0 (bottom-left panel) or f_v = 1.4 (bottom-right panel) for the kinematic data; the lensing data are unchanged.
