[Ba/Fe] abundance ratios obtained in 261 RGB stars in 47 Tuc, plotted versus relative radial distance from the cluster center. Cluster half-mass radius, rh = 174 arcsec, was taken from Trager et al. (1993). Linear fit to the data is marked as the solid red line. Typical abundance error is shown as the vertical bar in the bottom left corner.
