Left: dependence of the bias on S/N_KSB computed without correction or matching pairs from the CANDELS-like simulations, which then also includes the impact of selection bias. The dashed lines correspond to the correction from Eq. (14) for each component. Right: dependence of the residual bias on the FLUX_RADIUS estimated from the CANDELS-like simulations. Here, we have applied the S/N_KSB-dependent correction from Eq. (14). The second component is slightly shifted for visualisation purposes.
