¥For beam-gas events,
there appear to be many prompt T0s.
¥The raw time difference
distributions are 240 ps wide.
¥Applying the slewing
corrections from PR01 (for those PMTs that were used in PR01) reduces the width
to 150 ps or 110 ps for each PMT.
¥Since the HV on the PMTs
are different in PR03, compared to PR01, we will need to optimize the slewing
parameters.
