Hi, Chris!

Thanks for letting me know - I will doublecheck.
I only use ROOT for getting the l/r asymmetry errors, after that I
propagate errors by hand (for the super-ratio). This is also done in
"show_ep_asym.C", I looked at that (at least that's the way it was a few
weeks ago)... After getting the super ratio, I also propagate the errors
by hand for GE/GM.
Anyway, I will looked into it, thanks again!
