Current sheet test (Komissarov 2004; Yu 2011) as described by the initial data in Eq. (72) on a x ∈ [−2,2] grid (f_CFL = 0.25) at t = 1.0 for B₀ = 0.5 and different resolutions. Two fast waves emerge from the original discontinuity and propagate outward with the speed of light (analytical position of the waves are indicated by dashed vertical lines). The order of convergence, 𝒪 is indicated according to Eq. (71). Top: MP7 reconstruction. Bottom: MC reconstruction.
