Comparison of the emerging line profile for the 358.1 nm line synthesized with different assumptions affecting the ionization balance of Fe against the Hamburg atlas. The dashed orange line shows the Hamburg atlas. The solid gray line shows the LTE synthesis, and the solid black line was synthesized with Fe treated in NLTE. Removing the UV fudge factors from the NLTE Fe synthesis results in the black dashed line. Including the fudge factors in addition to treating Si, Al, and Mg in NLTE (hence modifying the UV continuum) results in the green line.
