Upper panel: Comparison of temperatures derived from stacking with mean mass-weighted temperatures from simulations for the mock MAGNETICUM sample. Blue points show results from background subtraction, and black points represent results from background modeling. The red line shows the 1-to-1 relation, and the red shaded areas indicate the 1σ and 3σ error regions. Lower panel: Comparison of temperatures obtained for the observed sample (violet points) using background modeling and background subtraction methods. The red line represents the 1-to-1 relation, while the red shaded areas indicate the 1σ and 3σ error regions.
