Magnetic field amplitude along magnetic field lines |B(s)| [nT] computed at different local times (LT). LT 12 corresponds to subsolar longitude (yellow) and LT 0 corresponds to local midnight (dark blue). Panels (a)–(c) correspond to different equatorial distances from the center of the planet: 1.1 R (a), 1.3 R (b), and 1.5 R (c). Resulting values for the loss-cone angle from Eq. (3) are also shown in each panel. Plots done at a time of 15.9 R/V_x, which is the same as in Figs. 1–4.
