hi guys - good job on the successful daq tests...

feel free to power up tofp LV and HV whenever you want to.
but i definitely prefer that once it's on *it stays on*....

in that sense i wouldn't mind waiting a day or two or three
on the TOFp (L/H)V until the star daq and trigger and
the machine are in better shape....

onto other topics...

i moved all the dAu localmon files in tofp.starp:~tofp/daq/data to
~tofp/daq/data/run3_dAu and gzipped them...

i started localmon. by chance it caught a couple of strobe events
just after i started it.... data looks fine.
