The caustic and hydrostatic mass profiles for each cluster as black solid and green dashed lines respectively in the upper panels of each plot. The ratio of the hydrostatic to caustic mass, M_X/M_C, are shown in the lower panels of each plot. 1σ uncertainties are shown by the shaded regions. The vertical black line is at the value of R₅₀₀ as calculated from the hydrostatic mass profile; the solid red vertical line is at the outer radius of the measured temperature profile (note that hydrostatic masses beyond this radius are based on extrapolation).
