Temperature profile of J0723. Blue and red data points are from the analysis of eROSITA (after modification using hard-band results) and Chandra, respectively. The solid black curve and shaded area are the best-fit model of the profile. The two dotted lines indicate the positions of R₅₀₀ = 1.32 Mpc and R₂₅₀₀ = 0.54 Mpc, determined from the hydrostatic mass profile measured by eROSITA (blue line in Fig. 5, see Sect. 3.3, same for the other figures).
