Radial error $\widehat{R}-R$ on 100 electrons simulated S2s. A positive radial error means the S2 is localized further away from the center of the detector than the true position and vice versa. Both the DiNN and MLP model cannot localize S2s in R > 60 cm region as accurate as S2s in R < 60 cm region, resulting in a wider spread in R > 60 cm region and the positive radial error is suppressed by the constrained output in the region extremely close to the detector wall for the DiNN.
