Hi,

I want to know if there are any objections to me showing preliminary pion 
beam asymmetry plots for the MENU conference. I have shown the data 
below 1200 MeV in the past and have now pushed the energies to just under 
1700 MeV.

Beam asymmetries for gamma p -> pi0 p:

Beam asymmetry's for gamma p -> pi+ n:

NOTE: There are over 2800 CLAS data points shown. Each plot is clearly 
marked as preliminary. The red lines are SAID and the green lines are 
MAID. CLAS errors are statistical only. The world data shown is within +/- 
0.025 of the cos(theta_cm) value printed on each plot.

Thanks for your time.
