[Clas12_verystrange] Fwd: [Clas12_software] CLAS12 Pre-Release Coatjava 4a.7.5 and GEMC 4a.2.0

Hi,

I'm getting strange results and I would like to see if others are seeing 
something similar.

Using Coatjava 4a.7.5 and GEMC 4a.2.0 for the Xi^- K^+ K^+ reaction, I get 
for beta vs. momentum of charged particles:

* (using for beta and momentum: REC_Particle) 
the plot https://userweb.jlab.org/~dugger/vs/pidTest.png

At zero beta I get a bunch of garbage and there are not many protons.

If I neglect low values of beta:

* (using REC_Particle for momentum and constructing beta from 
REC_Scintillator and FT_particles information)
the plot https://userweb.jlab.org/~dugger/vs/tmpPID.png

It looks like there is good information in the files but the beta from 
REC_Particle_beta is messed up for me. In particular, protons are very 
messed up.

I probably did something wrong in processing the events but I wanted to 
check to see if anyone else is seeing problems.

Take care,
Michael
