Top panel: total pressure p_tot = 2n_ek_BT_c,e + p_mag in black, along with the electron gas pressure p_e = n_ek_BT_c,e in dark gray and magnetic pressure p_mag = ∣B∣²/2μ₀, computed with all quantities scaled to the perihelion distance of 35.6 R_⊙ (see Section 2.2), all in nPa. Bottom panel: electron β_e = n_ek_BT_c,e/p_mag, in black for calm solar wind intervals, and in gray otherwise. Here quantities are also scaled to 35.6 R_⊙.
