Came in to find the laser had tripped, presumably because of the site-wide power glitch.
Brought laser back.  Everything seems to be okay.  However both the reflected power and
the power sum measurement reported by the MEDM screen are out of whack.  It might be that
the power glitch fried the reflected power power meter similar to what happened the last
time power to the site went out - it took out the power meter in the external shutter.
The power sum might be a problem with the photodiode.

    Both might require restoration of the calibration factors from the snap files.
