This is because I was looking at all muon events which didn't have an NHIT trigger fire and I noticed the following events: Run GTID ---- ---- 10036 1462054 10040 2270713 10133 1096180 They all appear to be neck events, but the first one in particular has 4 neck PMTs that got hit. When looking into it I realized that all 4 hits had ept times of -9999. several events: --- src/dc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/dc.c b/src/dc.c index 0dadfc7..276d0e5 100644 --- a/src/dc.c +++ b/src/dc.c @@ -580,11 +580,11 @@ int is_neck_event(event *ev) switch (pmts[i].pmt_type) { case PMT_NECK: + n += 1; + /* Require good calibrations. */ if (ev->pmt_hits[i].ept <= -100) break; - n += 1; - /* FIXME: The SNOMAN companion says "Early if defined by the neck * tube having an ECA time 70ns or more before the average ECA time * of the PSUP PMTS with z les than 0."
