Choose kinematical variables

fixed value for Wcm (MeV) 
choose a final state partition 1 + (2 3) : p1 + (p2N)  p2 + (p1N)  N + (p1p2)
choose an independent (running) variable:
q1  (polar angle of particle 1 in the gN c.m. system)
M23 (invariant mass of subsytem (2 3) )
and the number of points of the running variable
