flashing IMC, then no light
I was mproving the flashing in the IMC, and then something happened, and there was no light into the IMC.
I collected 14 seconds of data on channels I think might help an expert explain, and have attached the plots.
NPRO is running, and OSC_PD_AMP_DC_OUT shows 35W, so that part of the laser in on.
