Example spatially and temporally averaged, disc-centre synthesised Sc i, Sc ii, Ti i, Ti ii, V i, Cr i, Cr ii and Mn i line profiles (blue dashed), shown in comparison to the observed FTS profile (solid green). We removed the solar gravitational redshift from the FTS spectrum, convolved the synthesised profile with an instrumental sinc function and fitted it in abundance. Wavelengths and continuum placements have been adjusted for display purposes. Plotted profiles are computed in LTE, but quoted abundances in each panel include NLTE corrections computed in 1D (wherever available).
