We took measurements of LC1 fast-axis angle.

We installed LC1 and measured the power after a cross-polarizer for various rotation angles while varying the LC1 voltage from 0 to 25V.

What is a bit surprising is that the fast-axis direction seems to be more sensitive to applied voltages compared to previous measurement.

This is visible in the figure with all fits. to be uploaded when logbook is able to.

In any case we measured fast-axis at 45.49 +/- 0.69 deg which is compatible with previous estimation.
