and S/N is the signal-to-noise measured in the wavelength region of the particular line being measured. For a stronger line (EW $\sim 100$ mÅ) then whereas weaker lines (EW $\sim$ 20 mÅ) yield a value closer to 10% we conservatively adopt 10% as the uncertainty in EW measurements for each line.

EW Comparison with Standard Stars {#sec:EWcomp}
---------------------------------

To test the validity of the analysis procedure, two standard stars are analysed using the same method as the target stars: M3-C41303-2217 and M13-III-18. Fig.s \[fig:EWCohenm13\] and \[fig:EWCohenm3\] show
