reduced power send to PMC to 17W
At 2pm we transitioned the LAE to commisioning mode again. As Rick recommended we increased the temperature inside the room to match with the temperature in science mode operation. 

We reduced the power send to the PMc to the same level available in Low-Power-Mode (14W) and adjusted the PMC, ISS and FSS loop to that power level. We have not turned the high power oscillator off, yet, to perform a set of DBB measurements tomorrow morning. 

The DBB had to be realigned because of wrong settings in the snap file which was loaded after the power outage this weekend. 

I also adjusted the half-wave plate downstream of the PMC to send 1.5W in the IO path and checked that the power in front of the lower periscope mirror was only 0.94W. 

At 5pm I switched back to science mode operation of the LAE.

I also measured the power in transmission of the FSS available at the ALS, that is 12mW now.
