Resulting p-values of the Kolmogorov-Smirnov tests comparing reconstructed time series distributions with exponential distributions, for measurements taken during low and high magnetic activity periods whose dates are listed in Table 2. Triangles stand for ℓ = 0 modes, squares for ℓ = 1 modes, and circles for ℓ = 2 modes. Brown and pink makers stand for tests on values taken during high (resp. low) magnetic activity. The threshold of rejection of 5% is drawn as a dashed black line.
