keyword=R-arm T1 seems to be double counting
The right arm still has 49% deadtime even at low rate, and slightly higher at
high rate (54% at 1.6kHz DAQ rate). Looked as though the T1 may have been
double counting, and by looking at the scalar sum, this appears to be the case.
Run 4845 had beam off for most of the beginning, and for 40+ scalar reads, T1
was always an even number (while everything else varied). Looks like a double
pulsing or double counting issue.
