Hi Paola,
Thank you for the new information, and corrections to the groups. Here
are my corrected results. The 'normal' case is without PEATHRESH. I
agree that the kink near 19.6 MeV is not as dramatic as one of the
original figures suggested, due to binning. However, there is (was)
also a kink near 400 MeV, where there was no change in binning. In my
opinion, one or both kinks are still present in the figure you showed.
However, the PEATHRESH option essentially removes the kinks, and hence
that issue. My new plots are adjusted for the equivalent of equal
binning in momentum, rather than kinetic energy.
I have also attached a figure of the neutron momentum distribution over
the full range, communicated to you privately earlier. There is a
change in slope above 6 GeV/c with the PEATHRSH option. You responded
that the old model had a change in algorithm at 5 GeV/c, and the new one
is valid over the whole range. I guess I'm a little surprised that the
new model has a bend, whereas the older model does not. I don't have
data handy for comparisons, and I'm willing to accept it as being
correct. So I'm basically ready for production.
Thank you,
Best regards,
Joe
