Residual column density maps of the stellar disc distribution within our model compared to two analytical models. The left panels show the comparison with the S22 analytical model, while the right panels compare with the analytical potential from R17. In both cases, the residuals are presented in the xy, xz, and yz planes. Overlaid on the maps are contour plots representing cumulative fractions of the total stellar mass our model: 10%, 25%, 50%, 75%, and 90%.
