keyword=Deadtime from ROC17 scalersTrying to calculate deadtime with ROC 17 scalers that are read every event.
Trigger is HRSsingles or DVCS clock (input is T7 LED clk, output is T9)
T7 was added later to ROC 17
used left_t9c to estimate dvcs clock rate as 1.1e-4*(103.7 kHz clock)
I subtracted first event offsets from all scaler values.
