Inversion fits to the averaged line profiles for the observing season 2008. Panel a) shows the Zeeman-sensitive Fe i 6173 line (effective Landé factor geff = 2.50), panel b) shows the Zeeman-insensitive Fe i 6240 line (geff = 1.00). The dots are the PCA-enhanced observations, the lines are the inversion fits with a total of six free parameters. The respective lower panels show the residuals enhanced by a factor of ten. The average magnetic flux density is 542 ± 72 G.
