Flattening commands and Interaction Matrices: creation of Cx, obtaining shapes Sx

Keywords:

• Temp ATT: command given to the PID controller
• T Adsec: temperature read on the cold plate inlet
• Intmat: located in $ADOPT_MEAS/adsec_calib/flat/
• Electrical data: located in $ADOPT_MEAS/adsec_calib/flat/xxxxx/flattening_result.sav
• Optical data: located in $ADOPT_MEAS/adsec_calib/4d/flattening/xxxxx.h5
• WFE: residual wf error after 4 terms removal (pisto, tip tilt power)

Notes

Housekeeper variables:

• Main inlet and Main Outlot are switched
• Water CP inlet and Water CP outlet (THIS IS THE REFERENCE TEMPERATURE FOR THE TEST)
• Fluxrate is read as 0. ATT fluxmeter reads 0.25 l/s
• before flattening with an old intmat, a shape obtained at a different temperature is loaded (300 nmRMS approx...)

The Adsec Swing Arm cabinet is not cooled, to avoid condensation
