Deprojections by the constant moving bins method of several realizations of a sample projected from an initial Gaussian distribution with peak position 150 km s−1 and standard deviation 50 km s−1 (Nv ≈ 12 000 points, Ns = 25 realizations). We show the mean deprojected distribution (black curve) and the ± 1σ limits (greencurves) compared with the initial distribution (red curve). The quality of the deprojection is clearly improved compared to the 1200 points case, in particular concerning the peak amplitude (Fig. 9).
