Maps of inclinations returned from S1 inversions for the spatially and spectrally degraded synthetic profiles, with no noise (left) and two different noise levels (8 × 10⁻⁴I_c, middle, and 3 × 10⁻⁴I_c, right). Only Stokes vectors with a maximum amplitude > 3σ_n are retained after PCA. Black areas are representative of pixels which do not reach this threshold. The lower row shows the maps for V1 (FWHM = 0.53″) while the upper row shows the same for V3 (FWHM = 0.3″, with stray light included in the estimation and application of spatial PSF). The arrow in the upper left panel indicates the spatial location of the sample profile shown in Fig. 11.
