Coating measurement with more averaging

I read a paper which said that Jones matrix measurement can be improved with more averaging. Although they measure a sample which was changing its properties in time. its quite different. But, still wanted to try to save with more averaging. So I did 100 averaging of each point. Also, had to take measurement again after amending flaws in the averaging./

So, I scan the LC voltage from 0-3.5V with 0.1V step.
