A disagreement between the values of iron-to-hydrogen ratio derived for the prototype super-metal-rich K giant, Mu Leo, from visual spectroscopy, on the one hand, and from narrow-band photometry and near-ir spectroscopy, on the other, is investigated. It is assumed that the disagreement is related to the measurement and analysis of equivalent widths rather than the choice of effective temperatures, surface gravities, and model atmospheres. Synthetic spectra for two model atmospheres of different metallicities are generated and convolved with the appropriate turbulent and instrumental broadening functions. Equivalent widths are measured from these spectra and used in a differential curve-of-growth analysis in an attempt to verify the known metallicity difference. Comparison with previous spectroscopic analyses of Mu Leo indicates that systematic masking of metallicity differences is a consequence of line blending in crowded spectral regions.
