B_LOS, derived via MILOS inversions, from the Stokes profiles shown in Fig. 2. Top row: μ = 1, bottom row: μ = 0.5 in the ‘positive viewing’ direction with spatial foreshortening applied. The B_LOS maps are shown at the original MURaM resolution, SO/PHI-HRT resolution at perihelion, SDO/HMI resolution and SO/PHI-FDT resolution, also at perihelion. The spatially averaged value of B_LOS is inscribed at the lower-right in each panel. The black squares outline the region considered in Fig. 7.
