Scaled hydrostatic mass profiles derived in this work and from the suite of cosmological simulations published in Le Brun et al. (2014), shown with coloured and grey solid lines. The black error bars represent the 68% dispersion of the simulated profiles computed at 0.1 and 0.5 . Simulated and X-ray mass profiles were scaled by their and , respectively. Our sample and simulated cluster radial profiles were scaled by their and , respectively. The common scaled radius is indicated with R₅₀₀.
