Parallel (top panel), Hall (middle panels) and Pedersen (bottom panels) conductivities for Trappist-1 b (left column) and π Men c (right column). The contribution of electrons is shown in black solid lines, the individual contributions of ions in colored solid and dotted lines, and the total conductivity is shown in dashed magenta in each panel. For the Hall and Pedersen conductivity, a constant planetary field of 0.2 G has been assumed throughout the upper atmosphere.
