Local analysis of turbulent properties inside and outside the flux rope for RUN A and RUN D. Top: flatness F(r) of magnetic field increments as a function of separation scale r for RUN A (left) and RUN D (right) and for data sampled inside (red) and outside (blue) the flux rope. Dotted line is the reference Gaussian flatness value. Middle: scaling exponents ζq as function of order q for RUN A (left) and RUN D (right) evaluated inside (red) and outside (blue) the flux rope for the magnetic field. Dotted lines represent the linear scaling, while solid lines indicate the p-model best fit for each data sample. The Hurst exponents h = ζ2/2 are 0.42 (inside) and 0.35 (outside) for RUN A and 0.40 (inside) and 0.42 (outside) for RUN D. Bottom: Politano-Pouquet’s term Y(r) as function of separation scale r, computed inside (red) and outside (blue) the flux rope for RUN A (left) and RUN D (right). The dotted lines indicate the linear scaling. Filled circles correspond to −Y(r) and empty circles to Y(r).
