Dear Adam 

I went through your note that seems to agree with our computations (after we take care of notation differences). Just
two points: I believe we need a normalization coefficient in front of the B's in (6) as in equation (4) of my note?  It is not
clear to me how the B's (you called B_H, I believe) are written in the reflectivity basis? Perhaps for the pKK case it will good to start 
using the helicity basis?

Another practical question is that for equation (4) Will we get the full B as a function of s_D , t_1  theta and phi (GJ)? I suppose the data by SAID
have to be recalculated in those variables since is in the K-p CM? If we get functions for the  B's as function of the GJ angles (for given s_D and integrated over t_1,
Iwe will get ready to include them in our PWA code.  In principle we also will need several sets of B's (for K-, for  K+ and K*?) ro it will be good enough to start with only one set?

We will have our JLab-PWA meeting this Friday to continue this discussion. Thank you.
-Carlos
