Notes. ξ is the microturbulence velocity. For the criteria used to classify stars as ‘no s-process’, ‘mild s-process enrichment’ and ‘strong s-process enrichment’, see Sect. 4 of Karinkuzhi et al. (2021b). In the column ‘Remark’, we identify two stars where a Li abundance could be derived (‘Li’ if the Li abundance is subsolar and ‘Li-rich’ if it is super-solar).
