Cosmic ray runs

During the June run quite a bit of cosmic ray data was taken while we were
waiting for the beam. I have sifted through the run sheets and have
compiled the following (quite incomplete) list of runs:

Run # Triggers Trigger file Notes

3805 137000 MinDEDX_tof_ecallow_async_sect123456.trg Tagger comm.
3803 64000 "
3801 120000 "
3692 400000 Electron_EC_sect123456.trg 400 mV thres.
3682 391000 Electron_EC_sect123346.trg "
3507 420000 ???

I don't know how useful these are going to be. The voltages on the
counters changed a few times during the course of the June run.
Nonetheless we can still work on counter-to-counter timing using some of
this data.

I tried to pick out the longer runs or runs with definite trigger
conditions.
