Fits to the disentangled spectra and resulting posteriors of the average small-scale magnetic field strength. Top: Studied Ti I lines, with observations in black, the median parameter model in red, and non-magnetic spectra with otherwise identical parameters in dashed blue. The two rows correspond to the primary (first row) and secondary (second row) components. Bottom: Posterior distributions of the average magnetic field strength of the two components, with the median and 68% credence regions marked with vertical red lines.
