Examples of fits (upper panels) with the corresponding projections (lower panels) at time T₄ = 1.31 Gyr. The resulting parameter ratio r_t/r_J is given in the upper panels and the (l, b) coordinates in the corresponding lower panels. In the upper panels, the solid (black) line represents the data and dotted (blue) line the fit. The dashed (red) lines mark r_c (left dashed line) and r_t (right dashed line) from the fit with Eq. (6). In the lower panels, the dashed (red) line marks r_J.
