Notes. The column ESPaDOnS lists the abundances derived using the original ESPaDOnS spectrum. The column UVES, lists the abundances derived using the spectrum degraded to the UVES resolution, with the original S/N. The last two columns give the mean abundances and their standard deviation, obtained from the 101 Monte Carlo simulations for the low and high signal-to-noise hypothesis.
