Scatter plots of pairs of solar wind, turbulence and wave parameters (see Tables 1 and A.1). Blue, red and green points indicate intervals of group 1, 2, and 3 respectively. Blue open circles in the bottom central and left panels represent intervals with wave zero parameters, for clarity, their value is set to 0.1 in order to be represented in the logarithmic vertical axis. Vertical and horizontal lines indicate standard fluid turbulence reference vales. The correlation coefficient is indicated (Table A.2).
