Same as for Fig. 1, but for IC 10, and, as before, with H_E green, Y_E red, and I_E blue. Extinction has been corrected and sky subtracted as described in the text (Sects. 3.2 and 4.1). In the top left panel, the full FoV of 0.7 × 0.7 is shown, while in the lower one the inner 6’ × 6 ‘ region is displayed corresponding to the white box in the upper left panel. The top right panel shows the zoomed-in 30ʺ × 30ʺ RGB image of the blue nucleus also seen in the radial color profiles (Sect. 4.4, App. C, and Fig. C.1); the white box in the lower panel corresponds to the zoom-in cut-out shown in the upper right. The dark boxes in IC 10 result from an incorrect orientation of the instruments relative to the roll angle of the satellite during observation (this was the first galaxy observed within the ERO Showcase).
