Distribution of orbital weights along short axis. Top: circularity λ_z of the used orbits versus radius. We show a combination of the five best-fitting models. The dotted lines show the effective radius FCC 47 (R_{eff, FCC 47} = 30″, Ferguson 1989). Bottom: profile of the mass fractions of rotating (yellow), hot (blue) and counter-rotating orbits (red). The solid lines show the combination of the five best-fitting models (dashed lines).
