Ring Heater turned on for cavity scan

(Jax, Elli)  At 13:59:25 local time (20:59:25 UTC) 630mA was requested from each segement of the ITM. Cavity scans are being recorded.  We'll turn the ITM ring heater off after 3 hours.

Running the ring heater is affecting the alignment of the cavity a lot, I'm having to increase the pitch offset on the ITM by about 25 counts every 2 minutes.  Wavefront sensors are on.
