Notes. L11: this work; Qiu01: Qiu et al. (2001); HBA97: Hui-Bon-Hoa et al. (1997); RH97: Rentzsch-Holm (1997); HL93: Hill & Landstreet (1993); HS93: Holweger & Stürenburg (1993); L90: Lemke (1990); SU89: Sadakane & Ueta (1989), LRB82: Lambert et al. (1982). Values marked with an asterisk are omitted from the mean abundance and standard deviation (SD) of the listed results for each element, tabulated in the second last column. The last three lines give the value of Te in K, log g in cm s-2, and the microturbulent velocity parameter in km   s-1, for each analysis included.
