keyword=paddle 2 electron armSo here are plots of tc_cor and tcl gated on either the larger peak in the
electron-arm paddle 2 spectra, OR on the smaller peak. Upper plots
are for the big peaks. The problem is definitely there ... the right side
appears to have no irregularities, and timing left against right clearly
displays the problem. It reconstructs to the proper place in tc_cor, but
as one can see from figure 1, randoms subtraction is unnaturally constrained
to a smaller subset of the bucket unless a special analysis path is defined
for this subset of events. Ugh.
.
Analysis of raw tcl spectrum shows that the peak moves by about 10 ns.
These guys are all gated against the self-timing spike.
