We are running with ps1=1 and the others "infinite".
L-HRS run 25308 and R-HRS run 4836.
The T1 rates, L1A rates, and deadtime are approx:
R-HRS T1 = 840 Hz, L1A = 400 Hz, deadtime = 52%
L-HRS T1 = 2600 Hz, L1A = 1900 Hz, deadtime = 28%
Another L-HRS run was started. Run 25309.
The L-HRS deadtime looks ok, but the R-HRS looks high.
I noticed even for cosmics the R-HRS deadtime was 28%.
Might be double pulsing somewhere.
