Comparison between the effective radii R_e measured by MTO and the values reported in the literature for the dwarf candidates we used to train our model. We show the literature values on the x-axis and the values measured by MTO on the y-axis. Both axes are shown on logarithmic scales. The data points are color coded by the survey they were identified in as shown in the figure legends. The one-to-one relation is plotted as the gray dashed line. We compare our measurements in the individual bands with the single values reported in the literature. Left: g band, center: r band, and right: i band.
