(a) Scatter plot of J_sh/J_ab versus r_B for spectral types in path #1 (black), path #2 (red), and the TPL (green) type. (b) Proportion of events with J_sh/J_ab peaking in the sunward, perpendicular, and antisunward direction, as well as events with roughly isotropic J_sh/J_ab. (c) Histograms of E_drift. (d)–(e) Median electron drift length L_drift (d) and drift time T_drift (e) versus downstream electron energy. (f) Histograms of D_ramp. (g) Scatter plot of D_ramp versus T_drift for spectral types in path #1 and the TPL type. (h) Scatter plot of E_drift versus J_sh/J_ab. (i) Histograms of D_g/D_ramp, where D_g is the electron gyrodiameter at the spectral break energy. For the TPL type, the higher break energy ε₂ is used. In (e) and (g)–(h), pink, light blue, dark blue, and orange indicate UDPL, SPL, DDPL, and ER types in path #1, respectively.
