Kinetic properties of identified anticorrelated structures in different groups. (a)/(b) Monotonicity of proton speed and temperature quantitatively described by Spearman’s rank correlation coefficients. (c) Two-dimensional distributions of proton speed and temperature for anticorrelated structures (scatter) and solar wind in 2001 (histogram). The bin width is 10 km/s and 5000 K. (d)/(e) Proton-proton collisional age and corresponding monotonicity. (f)/(g) Plasma beta value and corresponding monotonicity. (h) Two-dimensional distributions of proton-proton collisional age and plasma beta for anticorrelated structures (scatter) and solar wind in 2001 (histogram). The bin sizes are uniform on the logarithmic scale, for each bin, ${\mathrm{\Delta }}_{{log}_{10}}^x=0.0475$ and ${\mathrm{\Delta }}_{{log}_{10}}^{\mathit{y}}=0.0525$.
