Here I am looking at the Veto - HTRIGT timing differences by run number for Veto counter #2, top pmt.
Below are the fitted time differences and the widths.
Data production starts after run 4100. The outlying pionts and those with a mean of zero are from junk runs with little or no statistics.
In this plot, I zoomed in on the good runs to see if the calibrations changed abruptly.
Next, I am extracting the TDC offsets for each run range. Below are the constant fits for the first three run ranges.
