Maps of synthesised Stokes I/I_c and V/I_c profiles for the λ₀ = 6173.3 Å absorption line for one snapshot at ⟨B_Z⟩ = 200 G at different spatial resolutions. Left to right columns: Original MURaM resolution, resolution of SO/PHI-HRT at perihelion, SDO/HMI resolution, and resolution of SO/PHI-FDT at perihelion. Top two rows: maps at μ = 1. Bottom two rows: maps at μ = 0.5 in the ‘positive viewing’ direction with spatial foreshortening applied. Top and third row: Stokes I/I_c at dλ = −0.35 Å. Second and fourth row: Stokes V/I_c at dλ = −0.07 Å. The black squares outline the region that is considered in Fig. 7.
