Surface brightness profiles in SDSS r band for Apollo (top left), Artemis (top right), Atlas (middle left), Ben (middle right), Castor (bottom left), and Daphne (bottom right). Blue solid line: “observed” SB profile using the SUNRISE (Jonsson 2006) mock images; those images can be seen in Few et al. (2012). Red solid line: single/double disc fit. Green, vertical, solid lines: these lines delimit the extent where the fit has been performed. Black vertical solid line: Boundary between the spheroid component and the disc; it is computed as the point where the distance between red and blue solid lines is less than 0.1 mag arcsec^-1. Red, vertical, dashed line: location of the break.
