Table F.1.
Element abundances determined for the identified PAGB star. The abundances are estimated as logε = 12 + log(nX/nH) and [X/H]=log(nX/nH)−log(nX⊙/nH⊙). The solar values logε⊙ are from Asplund et al. (2009); σL is the standard deviation; 
is the final uncertainty, accounting for inaccuracies in the model parameters; N is the number of averaged lines.
