Smoothed map of the mean density pattern for point-like (top-left) and extended (top-right) objects with 1.1 <g−r< 1.6 in standard coordinates, discarding 3σ outliers, with σ being the standard deviation between the different pointings. The bottom panel plots the ratio of point-like/extended objects, showing the spatial gradient in the morphological misclassification when moving away from the centre of the pointings. The error-bars indicate the standard deviation of the ratios derived from the different measurements in all the pointings.
