We have performed an analysis of the 
data in the region of the and resonances which have a substantial overlap and require special care. By using the 
model to relate the different production modes, we make predictions for production of these channels and compare with experiment and other theoretical approaches. As a side effect we find that these resonances qualify largely as 
states and the weight of the meson–meson components in the wave function is very small.
