¥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.
