Properties of MCs observed at 1 AU versus the location angle (λ in degree). The correlations are shown for the mean MC velocity (V in km s^-1), the MC radius (R in AU), the axial magnetic field strength (B₀ in nT), and the axis inclination (i in degree) for the full set of MCs. λ > 0 and λ < 0 are shown in red and blue, respectively, and the abscissa, |λ|, allows comparing the two leg sides of the flux rope (Fig. 1c). The straight lines are linear fits to the data points (MCs) showing the tendency. The results with the total MC set are shown in black (linear fit and top labels). c_P and c_S are the Pearson and Spearman rank correlation coefficients, respectively, and “fit” is the least-square fit of a straight line (in black) to the full data set.
