[Frost] Updated my analysis page

[Patrick Collins]

Igor,
I have Mark Paris's predictions for the W = 1771 MeV, but not the W = 1827 MeV. I will update the 1771 plot soon.
Speaking of Mark Paris, does he have any predictions for the helicity asymmetry of the omega?

Patrick
P.S. For anyone interested, Mark's paper is PHYSICAL REVIEW C 79, 025208 (2009)
