Summary of the analysis for HD 198478. The subpanels of the top five rows show the observed spectra (solid black line) and synthetic model (dashed green line) in different diagnostic windows used in the analysis of our sample. Within each window, the purple horizontal line indicates which subregions have not been masked in the analysis. The subpanels in the bottom two rows are the associated probability distributions of each of the parameters derived in this work. The vertical dashed red and orange lines indicate the maximum and median of the distribution and associated uncertainties.
