Even though the voltages are being used from the file, it seems there could be a deviation, considering we did the calibration of LC 2 months ago. I can't see a zero crossing in azi and ell, also the file is a bit huge, so it will take longer than expected.

I am going to instead do scan using the voltage range estimated but without using the file, and doing first a rough scan, and then will later do a finer scan.

The voltage range estimated from characterization is 7-8 V for LC 1 and 0-25V for LC2 with condition of 2 degrees on azi and ell. 

So, doing a scan from 6-9V with 0.2V step, and 0-25V, 0,2V step.

(could see zero crossing in labview, still need to plot, measurement finished by the time I finished writing this elog)
