I was informed that the laser had tripped this morning.  Not sure exactly why the laser tripped as TwinCAT indicated
that the EPICS alarm was triggered.  At first glance it looks like the flow in head 3 caused the trip.  It reached
the trip value (0.4 lpm) roughly 2 seconds before heads 1 and 2.

    Attached are other trends of the laser power(s) versus the flow rate in head 3.  There is some evidence to
suggest that the NPRO might have tripped first, triggering the power watchdog for the front end (mis-named
Head2NPROa.png).
