Properties of EB 1 and surroundings. Upper row from left to right: intensities in broadband (BB), in Hα_wing on logarithmic scale, and line minimum of IR 1.5648 μm line (IR I_min); lower row from left to right: magnetic field strength including polarity from separation of Stokes V lobes (B_sep), LOS velocity from Stokes V zero crossing (υ_zc), LOS velocity from Doppler shift of minimum of IR line (υ_min), positive velocities are away from observer. Terrestrial north is up, limb to the left; see text for black crosses.
