Table 1: Parameters of the Gaussians fitting the U distribution of stars from Famaey et al. (2005), in the V-strip corresponding to the Pleiades, $-28 \le V$ (km s-1) $\le $ -18. The parameters ki give the relative fractions $N_i/N_{\rm tot}$, where Ni is the total number of stars in component i, and $N_{\rm tot}=1176$ is the total number of stars in the V-strip. The fraction fs is the relative fraction of stars from the Pleiades moving group with respect to all stars in the restricted $\pm $ $1.4 \sigma _{U}$ range around the Gaussian average, corresponding to the Pleiades zone where the wavelet coefficients are nonzero at scale 4 (see Sect. 3).
