Hydrostatic equilibrium (HSE) mass profile estimates for ACTJ0240 inferred using NIKA2 and XMM-Newton data. The solid magenta and green lines are mass profiles estimated by combining the X-ray density profiles (right panel Fig. 3) and the NIKA2 pressure profiles P_gNFW, NP (Fig. 5), in the scenarios where the PS is masked, and modelled, respectively. The shaded areas depict the 16th and 84th percentiles of these estimates. Blue, empty markers correspond to the mass profile inferred solely using the X-ray data, with their 1σ uncertainties.
