Footprint of the HSC-Y3 weak lensing dataset (grey dots) and the sky distributions of the eRASS1 clusters together with those categorized based on the availability of weak-lensing shear profile g₊ and/or the BCG stellar mass estimate M_⋆, BCG. The eRASS1 clusters with available g₊ are marked as blue circles (23 clusters), those with M_⋆, BCG as green diamonds (28 clusters), and those with both measurements as red squares (73 clusters). The other eRASS1 clusters with neither g₊ nor M_⋆, BCG are shown as grey crosses, and are excluded from this study.
