Notes. The moments of the 1-NNS distribution are given for: all stars in the whole Taurus region (sample S1, see Table 1), stars within the Win window (sample S2, see Table 1 and Fig. 1), the random theoretical 1-NNS distribution “Rand. Theo” in an infinite medium wR(r) = 2πρrexp(−πρr2) (Eq. (B.1)), and the 1-NNS distribution obtained from the 10 000 random Monte Carlo samplings “Rand. MC” within the Win window. The two random distributions are computed using the same intensity process ρ = 5 deg-2 (see Eq. (1)). The uncertainties are evaluated from Eq. (5), with N = 252.
