Chandra,

Interesting results. I have a few comments.

1. All new polarization results on slides 19-24 should be labeled as 
preliminary.
2. In some kinematical bins uncertainties in the polarization are close 
to 1 or even greater than 1. Showing them only causes confusion. When 
you show P=X+/-1 this means polarization is unknown. I suggest to remove 
those points from the plots.
3. Talking about QGP with respect to the photoproduction on the nucleon 
at photon energies of a few GeV is a bit of a stretch, energy density is 
not high.
4. What exactly do you mean by polarized hyperon can be used as a beam?
5. In conclusion you say "negative" polarization for Sigma^+ while use 
"+evly" polarized for Sigma^0. "+evly" does not look good. Simply write 
"positively".
6. On the title slide CLAS collaboration should be mentioned.

-Eugene
