  \caption{Effects on logarithmic abundances derived when changing the fundamental
  parameters of the model atmospheres. Two stars of different parameters are presented.
  The parameters (${T_{\rm eff}/ \log g/{\rm [Fe/H]}/\xi_{\rm micro}}$) are, respectively:
  (${\rm 4190/1.0/{-}1.75/1.3}$) and (${\rm 6300/3.97/{-}2.06/1.1}$).\label{error1}}
