Note: Abundances and their uncertainties -- 
if not noted otherwise -- are given on
  the usual logarithmic spectroscopic scale where $A$(H$)=12$.
Column~(1) is an identification flag, DI means Delbouille and NI Neckel disc-centre spectrum,
NF Neckel and KF Kurucz flux spectrum;
Col.~(4): hafnium abundance, $A$(Hf), according to the
\cobold\ 3D~model;
Cols.~(5)$-$(8):  $A$(Hf) from 1D~models,
with $\xi$, micro-turbulence, of 1.0\kms;
Col.~(9):  uncertainties related to {\it EW} measurement;
Col.~(10)  \citet{lawler07};
Col.~(11): 3D~corrections;
Col.~(12): uncertainty of the theoretical equivalent width due to the
limited statistics obtained from the 3D~model;
Col.~(13): uncertainty in abundance due to the model uncertainty
in equivalent width.
