Field inclination and field azimuth from SPINOR 2D inversions at three photospheric layers. From left to right: log (τ) = −2.0, −0.8 and 0. From top to bottom: field inclination angle in the line-of-sight direction γ_LOS (°); field inclination in the local-reference-frame γ_LRF (°) after the disambiguation of the field azimuthal angle; ambiguous field azimuthal angle in the line-of-sight direction φ_LOS (°); and disambiguated field azimuthal angle in the local-reference-frame φ_LRF (°). The contours are the same as in Fig. 3.
