ITMX Ring heaters set to 2W/segment for 6am -7am tomorrow morning
I have set ITMX ring heater set to be 2W/segment for 6am -7am tomorrow morning. This is to check where the center of the ITMs are on the Hartmann CCD after Mitchell and I added a filter to ITMX HWS in alog 65847. On tmux session on controls user on cdsws12 using command 'python3 /opt/rtcds/userapps/release/tcs/common/scripts/power_adj_scripts/ring_heater_schedule.py ITMX -s 1353160818 -d 1 -p 2' and instructions in alog 62731.
See attached plot of RH test. It looks good. We don't need to change the pointing onto the CCD, it is central enough.
I've also attached a longer scale (first 2hours) power up plot from yesterday. Dan reports with the IR filter/mirror it's much easier to see the point absorbers using short scale HWS images of power-ups too, e.g 200 seconds plot. I used time just after move spots at 25W as this is after total pixel is stable.
