Left: mass-weighted temperature map of the A3391/95 analog system found in the Magneticum simulation. The units are in keV. The box size is 7 comoving Mpc h⁻¹ in all three dimensions. The solid yellow circle has a diameter of 1 deg to approximate the FoV of an eROSITA pointed observation. The solid green circles correspond to r₅₀₀ of the two clusters while the dashed green circles approximate their r₂₀₀. Right: oxygen-to-soft-band-ratio map constructed in the same way as for the eROSITA data (Fig. 12), here assuming a 40 ks eROSITA pointed observation with all seven TMs simulated with SIXTE without including background.
