MCMC fitting results with one- and two-dimensional projections of the posteriors of the σ_v–L_x scaling relation for the AXES-2MRS groups with more than four galaxies (black solid curves and contours), AXES-2MRS-XMM-s (red dash-dot curves and contours), and its Gaussian subset (green dashed curves and contours). We refer to Table 2 for details about each sample. Other details are the same as Fig. 15.
