[Astrid Hiller Blin]

Hi Igor,

It's W = 1.75 - I will specify that in the abstract to APS. I am more
interested in N* and Delta resonances; indirectly I'm using pion, two-pion
and eta production data for N* and Delta electrocouplings: do you think
this should be specified in the abstract?

Thank you!
Astrid
