Caption: Figure 9.

Distribution of GD-corrected positional residuals (ΔXNGC 2298, ΔYNGC 2298) as a function of g-band magnitude. The grayscale shading represents the local density of points, with darker shades indicating higher densities. The red solid lines with error bars show the mean positional offsets and the corresponding 1σ dispersions, computed within 0.5 mag bins.
