Notes:
  • NLTE calculations were performed with the grid of MARCS model atmospheres.
  • For Ti II and Fe I, collisions with H I atoms were treated with the Drawinian rates scaled by a factor of S_H = 1 and 0.5, respectively.
  • NLTE abundance correction for given Teff, log g, [Fe/H], [X/Fe] is obtained by linear interpolation in the grids.
