Hartmann results from power up from 2W to 20W

After being at 2W overnight we powered up to 20W this morning. Attached are HWS images comparing 2W and 20W. ITMY looks great. ETMY is showing a negative lens rather than a positive lens which is interesting as we saw the correct negative lens when running the ring heater test in alog62314. Could we be looking at the beam off the ITM? I'm not sure we misaligned the ETM after realigning in alog61715. This wil be a task for next week!
