Observed fluorine vs. average s-element enhancements compared with theoretical predictions. Circles symbols are as in Fig. 2. Solid lines are the predictions for a non-rotating 2 M⊙ TP-AGB with metallicities (labelled) mimicking those of our stellar sample assuming the standard 13C-pocket, according to Cristallo et al. (2015b; labelled F, FRUITY). Dotted line is the prediction for a non-rotating 1.3 M⊙ metal-poor model for the same metallicities in the hypothesis of a larger 13C-pocket (labelled T, Tail; see text). Small open squares in these lines mark the values predicted at different TPs. J-type AGB carbon stars have been excluded because they usually do not show s-element enhancements (Abia & Isern 2000). Typical uncertainties are shown. See text for details.
