Left: typical observed stokes profiles in Ca II 8542 Å (black) and the fitted atmosphere (colored). Using Eq. (3) we get a χ² value of 6, 9, and 5 for the three profiles respectively. The pixel locations of these profiles are marked in Fig. 6 with the same color coding. Right: inferred parameters displayed between log(τ) = [−5.5, 0]. The colors match the profiles on the left. The uncertainties for the same pixels based on Eq. (3) are indicated by vertical bars at their respective node.
