Notes: The contribution to the EW of Co and V, according to the 3D simulation, has been subtracted from the EWs in the last two rows (labelled with *). (1) identification flag to distinguish disc-centre to flux spectrum results; (3) thorium abundance, A(Th), according to the $\ensuremath {{\rm CO}^5{\rm BOLD}}$ 3D model; (4)-(6) A(Th) from 1D models, with $\xi$ , micro-turbulence, of 1.0 ${\rm km~ s^{-1}}$ ; (7) the uncertainty due to the EW; (8)-(9) 3D corrections; (10) statistical uncertainty of the theoretical EW; (11) corresponding uncertainty in abundance.
