Edges of galaxies as viewed in edge-on (left) to face-on (right) orientations. The galaxies were selected to have similar rotational velocities V_rot ∼ 145 km s⁻¹. Left to right: IAC Stripe 82 gri-colour composite image overlaid on a grey scaled gri-band summed image for contrast, surface brightness profiles in the SDSS g, r, GALEX NUV and FUV bands, g − r colour profile and the corresponding Σ_⋆ stellar mass density profile. The pink contour in the gri-image and the vertical dotted lines in the other panels indicate the edge of the galaxy.
