LC2 fast axis

[Shalika, Marc]

Measurements of LC2 fast-axis angle were done. The data was taken in cross polarizer setting. 

We measured fast-axis at 73.42°±0.52°. The angle is quite deviated from previous measurement which can be accounted due to the partially unscrewed LC. 

The second LC was then set at -45° from its fast axis, i.e 28.42°.
