Top panel: Simx profiles and their median. The profiles are shown with grey solid lines and their median with a black dashed line. The Simx profiles were extracted from a randomly chosen line of sight for each cluster. The red solid line identifies the median of the CHEX–MATE sample. The black solid line is the median of the CHEX–MATE sample assuming a 20% bias on the mass (i.e. each profile has been scaled for ; see Sect. 4 for details). Bottom panel: ratio of the median of the CHEX–MATE with and without correction for hydrostatic bias and the median of the Simx simulations. The CHEX-MATE median with the correction is shown with the red line and the median without it is shown with the black line.
