Fig. 2
Left-hand side: profiles of Fe i 539.32 nm, Mn i 539.47 nm, and Fe i 539.52 nm lines at the disk center, from top to bottom. The profiles are computed in the following model atmospheres: quiet Sun (dashed), faculae (dotted), penumbrae (double-dot-dashed), and umbrae (dash-dotted). FTS atlas profiles are overplotted (solid curves). Right-hand side: center-to-limb variation of the EW of the lines. Symbols distinguish between the EW resulting from different model atmospheres: quiet Sun (plus signs), faculae (asterisks), penumbrae (crosses), and umbrae (squares). Diamonds with error bars are values observed in the quiet Sun.
