Notes. Values obtained from the curves contrasted in Fig. 5. The first column indicates the period, where “min”, “asc”, “max” and “des” denote the phase (minimum, ascending, maximum, descending) corresponding to the cycle indicated by its subindex. The second and fourth columns show the correlation coefficients between the vp solar wind speed with γ-exponent and D-divergence. The third and last columns display the p-values related to correlation coefficients of vp with γ and D, respectively.
