Cumulative, bin-averaged histogram of (top row), (middle row), and δB_∥/δB_⊥ (bottom row) in the (β_∥, e, T_⊥, e/T_∥, e) plane. Histograms are cumulated over the quasi-stationary phase ( for HVLF, left column; for iPIC, right column). Here, δB = |δB|≡|B − ⟨B⟩_t| and , where ⟨…⟩_t denotes the time average over the interval used for the histogram. The spatial region considered and the curves are the same as in Fig. 5.
