Trigger signals

Scint and coinc logic signals, scope triggered on coinc (magenta)

Same, with TI busy signal (green)

Same, different timebase

Histograms of hit times in central bank of 16 straws

ADC-value=150 crossing (~approx ped + 5sigma)

3.5sigma crossing (approx ADC value 112 = (55 + 3x16.5))

ADC-value=100 crossing
