Continuum intensity map (upper panel) and Stokes V map (lower panel) of a quiet-Sun region near the limb observed by Hinode/SOT/SP. The inserts at 7° and 35° from the limb (red crosses) are centred close to the maximum viewing angles of the solar poles from the ecliptic and from Solar Orbiter, respectively. The enhanced contrast signal at 35° viewing angle allows for a superior determination of the atmospheric parameters. The grey scales of both inserts cover the same dynamic range, but are individually centred to their mean intensity values.
