Average weak-lensing mass biases as a function of the corresponding three-dimensional masses. On the left, the weak lensing masses are relative to their respective total mass; on the right, they are always related to the total mass of the DM-only runs. The top and bottom sub-panels show the mean relative uncertainties and the relative differences with to the DM-only case as a function of considered three-dimensional reference mass, respectively. The right panels display the distribution of the weak-lensing mass biases over all cluster masses. The dark and light yellow bands show the 10% and 20% differences, respectively.
