Comparison between the observed Stokes profiles (black) and the best fit found by the HELIX⁺ code (red) using two magnetized atmospheric components for the He I 10 830 Å triplet, a magnetized and a stray light component for the Si I 10 827 Å line, and a magnetized component for the Ca I 10 839 Å line. The telluric line at 10 832 Å is fitted using a Voigt function. The gray shaded area marks the wavelength region that is not fitted. The vertical dotted red lines indicate the central position of the redshifted flow component, which has a v_LOS of about 29 km s⁻¹. The vertical dotted black lines and numbers in parentheses in the Stokes I/I_c panel have the same meaning as in Fig. 1. The observed Stokes I/I_c profile shown here is the same as the profile labeled 8–09jun16.004 in Fig. 1.
