[Hybrid baryons] presentation with chi square plots

[Annalisa D'Angelo]

Dear Victor,
yes, the statistical significance of the difference between model A and 
model B is lower for higher Legendre moments
because the error increases more that the absolute difference.
However I understand we are looking for a sizeable presence of a 
structure at a fixed W value above the statistical error
for different Pn.
