I happened to notice on the laser MEDM screen that the NPRO power monitor is significantly off.  No corresponding drop
in the output power of the front end though.

    Just checked the gain for the channel that monitors the NPRO power.  For (currently) unknown reasons the gain changed
from -1.013e-3 to -6.24e-4.  Maybe this was the result of a BURT restore to an out of date value?

    I took the liberty of changing the gain back to the old value.
