Representative example of Stokes I/I_c and V/I_c profiles of a highly redshifted pixel close to the center of BP (b). The profiles are taken from inside of the white contour of Fig. 5. Lower two panels: observations (black dots) and best fit (solid red line) from a two-component SIR inversion. Upper two panels: synthesized profiles arising from the two atmospheric models obtained with SIR which coexist within the same resolution element. Atmosphere 1 (blue solid line) and 2 (red solid line) have a filling factor of about 0.7 and 0.3, respectively. The inferred average LOS velocity and inclination between −1.0 ≥ log τ ≥ −2.5 from this particular fit is v_LOS, 1 ∼ −1 km s⁻¹ and γ₁ ∼ 172° and v_LOS, 2 ∼ 6 km s⁻¹ and γ₂ ∼ 169°, for atmospheres 1 and 2, respectively.
