[La/Fe] ratios as a function of [Eu/Fe] ratios for individual stars in M 80 (large filled circles) compared to r-only field stars from Roederer et al. (2010; small empty squares) and to GCs with a dispersion in s-process elements. Blue-filled squares indicate the r-only component in M 22 from Marino et al. (2011), orange asterisks are used for the r + s component in M 22 (see Roederer et al. 2011; Marino et al. 2011), and green-filled pentagons are giants in NGC 1851 from Carretta et al. (2011b). The internal error bars refer to our present analysis of M 80.
