Dear Anna
I'll try to help understanding what you see, but first of all I have a
few questions:
a) the plots you sent, do they refer to the BEAMPART or the ALL-PART
binnings?
b) could you provide the magnetic field routine, or at least some guess
about its intensity and direction?
c) is the ARgon target Argon gas and if so at which pressure/density?
d) what is PROPANEL (composition? density?)?
As an observation, possibly unrelated to your question, a maximum
deflection per step of 40 deg is quite large and it could result in
relatively sloppy tracking. Also the requested boundary accuracy of 0.05
cm -> 500 um which is comparable or larger than the the thickness of
some of your volumes, again it is likely unrelated to what you observe
but it can result in inaccurate tracking.
Ciao
