For time lag s=0, we show the half-plane representing all distinct spatial directions; for time lag s=1, distinct directions now fill the whole plane. We also show the correlations in time at spatial lag (k,l WebThe shape of the Gaussian is shown in Fig. 3 which illustrates this distribution for various .The significance of as a measure of the distribution width is clearly seen. As can be calculated from (19), the standard deviation corresponds to the half width of the peak at about 60% of the full height.
