Abundance of barium in the Galactic globular clusters (compilation by Marsakov et al. 2019) and Galactic field stars (thin and thick disk stars: Guiglion et al. 2018, halo stars: Lai et al. 2007; Cohen et al. 2013; Roederer et al. 2014; Jacobson et al. 2015). Average [Ba/Fe] ratio obtained in 261 RGB stars in 47 Tuc is marked by the red symbol where the 25th and 75th percentiles and the average values are indicated by the horizontal bars, while the extent of the whiskers correspond to the minimum and the maximum abundance values observed in this cluster.
