Notes. The values obtained by Maisonneuve et al. (2011) are given for comparison. The Rayleigh limit amounts to 10-3 d-1 and 10-5 d-1 for the data used in this paper and those of Maisonneuve et al. (2011), respectively. ⟨ v ⟩, ⟨ v3 ⟩, and PBP stand for the first and the third moments, and the pixel-by-pixel method, respectively.
