At around 0:30 local, I increased the ring heater power on ITMY from 1.5 W (0.75 W each segment) to 2.5 W (1.25 W each segment) (see 29557 for previous step). This has to be cancelled by applying approximately an additional 400 mW on CO2Y (e.g., pre-heat level of 800 or 900mW).  This step should allow us to better compensate the residual lens observed at 50W.
