^a Ages and age uncertainties are obtained from formulae (8) and (9) using the abundances listed in Table A.1. The four ``Age'' columns give ages based on production rations  of Kratz et al. (2007), Sneden et al. (2003), Schatz et al. (2002), and Cowan et al. (2002) (in that order) according to Table A.2. The Solar ages are calculated applying r-process fractions as given in Table A.3.
^b Three independent measurements were obtained for this star which is the reason why certain chronometer pair/object combinations are listed multiple times.
