Left panels: probability distribution functions for some of the structural parameters of Do I from the Resolved Stellar Population (RSP) method: the half light radius r_h in angular and physical size, the position angle θ, and the ellipticity. Right panel: radial density profile within 3 r_h of Do I centroid. The number of stars per unit area is represented as a function of the galactocentric radius in arcminutes. The solid curve represents the exponential radial profile drawn from the favored structural model.
