NI DAS powers including North CP lens

Following the estimate of the CP cold lens (55895), I re-computed the required NI DAS (see VIR-0528A-22) power for compensating thermal lensing @ CARM null and the CP cold lens. Figure 1 shows the resulting RMS for both effects, while figure 2 represents the same quantity only for the CP Cold lens compensation. 


  • For CARM null operation: inner ring 0.62 W; outer ring 3.66 W;
  • For compensation of only the CP lens: inner ring 0.1 W; outer ring 2.1 W
