keyword=more on paddle 2, left armpaddle 2 "bad timing" events (small peak) are very localized on focal
plane (see fig. 1) -- red spectrum is gated on "big L2 peak", purple
is gated on "little L2 peak".
.
analysis of espace scint hitpatterns. have not verified Bob's assertion that
this satellite peak is due to multiple hits, but I have discovered a clear
difference which is shown in fig. 2. The left panels show the hit pattern
of plane 1, left side when gated on main L2 peak (top), satellite peak (bottom).
We are gating on peaks in plane 1, paddle 2, left side and can see that
this is well reflected in the hit pattern -- more than 95% of the plane 1,
left-side hitpatterns are "2" when gated on the S1-L2 peak (either the
main or the satellite peak).
.
The right side panels are similar except they show what is happening with
hitpattern for plane 2, left side. For events in the main S1-2L peak,
the hitpattern is mostly also paddle 2 in S2 on the left side. For events
in the satellite peak, however, the hitpattern indicates mostly paddle 3.
I wonder if these really are multiple hits? I will try to pull that out next.
