My post run analysis sheds a little more light on the monitor reported
burst. Of the 5 kept hits, the first has a huge discrepancy between ADCZ
and TDCZ, the second is a inter-SM muon, and the third I reconstruct with
a very much lower energy using VAXGS constants as opposed to the monitor's
VXMACB constants. Interestingly, the last two hits with energies of 80 and
35 MeV are not cut. Both look like downward going muons that stopped in
the boxes or near the box without triggering more than a couple of wires.
They are in boxes 1T01 and 3E14, so I put my money on stopping muons.

The single line entries are the monitor report, double line are mine.
The energy and position on the second line are the ADCZ and energy
reconstructed using ADCZ:
