Left: local λ_R profiles calculated for the total sample of PNe associated with M 105 (grey), its Sérsic component (orange), and the exponential envelope (purple). Horizontal error bars denote the bins in which λ_R was evaluated. Right: cumulative λ_R profiles, with the same colour coding as in the left panel. In both panels, the dotted grey line at λ_R = 0.1 separates fast from slow rotator regions assuming constant ellipticity (Emsellem et al. 2007). The vertical dotted lines are the same as in Fig. 11.
