Comparison of SDM and ME0 disambiguations on the SO/PHI-HRT image plane. The SDM is applied using information from the hmi.ME_720s_fd10 series and: Eq. (5) (panel a; see Sect. 4.1), Eq. (6) (panel b; see Sect. 4.4), and a combination of both Eqs. (5) and (6) (panel c; see Sect. 6.2). Agreement is indicated in black disagreement in white, whereas gray indicates pixels that are not considered in the comparison because the SO/PHI-HRT transverse field falls below the noise threshold; the 400 G isoline of the SO/PHI-HRT |B_los| is drawn as a solid yellow line; axes units are SO/PHI-HRT pixels.
