Hi Phil,
I agree with you. However, what I do not understand is why the omega 
"band" is diagonal in the plot, i.e. there is a kinematic dependence on 
the missing mass of the system. It may be a nuclear effect (I am not 
expert on this), or something else.
If the experiment was performed on a lH2 target, the omega mass seen as 
the pi+ pi- pi0 invariant mass, would not depend at all on the missing 
mass on this system.

Bests,
Andrea
