Confidence levels for the eROSITA-Chandra and eROSITA-XMM-Newton scaling relations for different subsamples, defined based on their cluster properties. Top: 1σ (68.3%) contours for the core-only and annulus-only eROSITA-Chandra and eROSITA-XMM-Newton scaling relations for the full band. The colors are explained in the figure legend. The best-fit results do not differ significantly for core and annuli cluster T for any instrument comparison. Bottom: 1σ (68.3%) and 3σ (99.7%) confidence levels for the eROSITA-Chandra scaling relations for high N_H > 5.59 cm⁻² (pink) and low N_H < 2.45 cm⁻² (blue) clusters. The median values of the subsamples are N_H = 1.72 cm⁻² and N_H = 7.96 cm⁻², respectively. The contours correspond to the full band. The 1:1 line is represented by the black cross. The best-fit results are very similar between clusters with low and high Galactic absorption.
