TCS benches calibration

Last week, we also preformed the calibration of the TCS benches.
Figure 1 shows the NI TCS power versus the wave plate angle. Second plot shows the CO2 power as a function of the ADV voltage.
Minimum power is about 50mW, maxumim is 9.2W.
Calibration factor is:
PNI(W)=4.814*TCS_NI_Power_DC - 0.117
Figures 3 and 4 represent the same quantities for the WI. Minimum power is about 80mW, maxumim is 14.8W.
Calibration factor is:
PWI(W)=6.137*TCS_WI_Power_DC - 0.099
The different values for the maximum power out of the benches may be due to a different diffraction efficiency of the AOMs.
