Three examples of MHs found with the automated search programme. The left column shows event 1, which is a linear MH with a field rotation θ < 1°. Panel A: magnetic field components in e2k coordinates. Panel B: magnetic field magnitude B_m and the background magnetic field strength B₃₀₀. Panel C: ΔB/B₃₀₀ = (B₃₀₀ − B₂)/B₃₀₀. The middle column shows event 2, which is a rotational MH with θ > 30°, and the right column shows event 3, which is a current sheet crossing with θ > 175°. The grey-shaded boxes show the width w (FWHM) of the structures.
