Hi Brad,<br>
<br>
Attached is a few plots taking a closer look at the spike at ~ 170 ns in<br>
the S2m R-TDC times.<br>
<br>
The first plot shows an overlay of the ADC for PMT 7 with one-track, dead<br>
time pulse removed, PMT 7 firing (TDC >0) and a T3 cut (black line), with<br>
the plot having the same cuts plus a cut on the TDC time ~ 170ns (red<br>
line). The blue line includes a cut > 0 on the ADC.<br></blockquote><div><br>Forgot to mention -- blue overlaps with the red histo (ADC values > ~500) <br></div></div><br><br clear="all"><br>-- <br>-----------------------------------------------------------<br>
