Fig. 4
Fe i and Fe ii abundances as a function of the excitation potential (χ), the logarithm of the reduced EW and the wavelength. The continuous red line is the regression between the quantities shown in each plot. The dashed line corresponds to the Fe ii final abundance derived according to M2. In all plots, the black asterisks correspond to the Fe i lines and the red filled triangles correspond to the Fe ii lines. Left: spectroscopic analysis for HIP 20205 using ASPL list. Right: spectroscopic analysis for HIP 20205 using MASH list.
