Hi Rob,
I'm sure you get systematics if you bin for doing the measurements of EW
(though I'm not sure about how big they might be),
and this is found also by Isobels student that is working on the Gimini
data. However, Gaston (who did the measurements) I believe did not bin
the data.
Cheers
Gabriele
