Relation between X-ray mass and richness (top panels) or amplitude (bottom panels) for the full sample including matched detections with the X-ray catalogue and new detections with X-ray flux estimate in the full redshift range, z ∈ [0.1, 2.0]. From left to right: detections from analysis in r-, Y-, and H-band. The different colours refer to the different redshift bins, as labelled in the plot. The redshift-dependent best-fitting relation is shown for typical redshift values representing the four redshift bins, z = [0.4, 0.8, 1.2, 1.6] (z increases from light blue to dark red) and with their 1σ error region. The best-fit parameters are also reported in Table 3. The redshift trend visible for r-band-based detections fades out for redder bands, where the scaling relations become consistent with no redshift dependence.
