Same as Fig. 8 but for the transverse component of the magnetic field B _⊥ . The vertical black arrow indicates the original distribution employed to produce the synthetic Stokes profiles: it is a δ-Dirac centered at 0, because the synthetic profiles were obtained assuming that the magnetic field is longitudinal/vertical (γ = 0) and therefore . Note however that the effect of the noise induces the inversion code to retrieve high values for the transverse component of the magnetic field (blue and red lines).
