Weak-lensing bias of our extraction model on synthetic shear profile simulations reproducing the HSC WL signal around eRASS1 clusters and groups, showing the calibration results on the simulation snapshots as black points and the interpolated trend as blue band. Contrary to the DES WL bias, the depth of HSC permits a good background selection at all cluster redshifts considered. The larger shape measurement uncertainties however contribute to the WL bias uncertainty even when accounting for the systematics floor from hydro-dynamical modelling uncertainties (green band).
