Comparison of elemental abundances from the literature and this work (filled circles) for the same stars. The y-axis shows the difference in abundance, [X/H]_literature – [X/H]_{this work}, plotted against the T_c of each element on the x-axis. Potassium (K) is excluded as it was not reported in the literature. The open squares and downward triangles show a direct comparison of abundances measured from HARPS and MIKE spectra using the same spectral lines and analysis methods applied in this study. The differences reflect both instrumental systematics and manual measurement variability between HARPS and MIKE.
