Property of the probability distribution , parametrized by the slope of the linear fit (see the straight black line in Fig. 5a). This slope is shown here as a function of two selected MC parameters. The MCs are first ordered by growing order of one parameter, then they are split into subsets of 20 MCs, shifting progressively the mean parameter to higher values. The two selected parameters are the flux rope radius (R in AU, top panel) and the absolute value of the inclination angle (| i |, bottom panel). The three curves represent the slope of the fit, with the black line corresponding to the mean value of R (| i | for bottom panel) for each subset, and the blue (resp. red) line corresponding to the minimum (resp. maximum) of R (| i | for bottom panel) value for each subset. The horizontal dashed line is the slope for all MCs (black line slope in the top panel of Fig. 5).
