Top: Score that the dwarf is classified as a dE as a function of the score that the candidate is a real dwarf. Bottom: Median score as a function of the source area from the annotation tool. The error bars represent the standard deviation in each bin. This plot provides the range of object sizes that we could more securely consider for the dwarf validation. It shows that early-type dwarfs get a better consensus and that too small or large objects tend to be excluded as dwarfs.
