a) Comparison of spectroscopic metallicities obtained in the infrared (this work) versus in the optical (Marino et al. 2009) for s-poor (open circles) and s-rich (filled circles) stars. Typical uncertainties are shown.b) [Fe/H] residuals (ours minus optical values), where the dashed lines represent 1σ scatter over the mean value found (full line).
