Comparison between eRASS1 and Chandra (left), XMM-Newton (middle), and spectroscopic eROSITA (right) temperatures. The comparison between the core-excised (core) T_Chandra/T_XMM/T_eRO,spec and the single T_eRASS1 from the entire R₅₀₀ is displayed in blue (green). The best-fit scaling relation lines are displayed with the same colors. The equality 1:1 line is shown in red (dash dot), except for the right panel, where it coincides with the green best-fit line. The blue and green shaded areas represent the statistical error plus the intrinsic scatter for the core-excised and core scaling relations respectively.
