Unknown Analyzer Follow Up Questions

~~1. Briefly describe your process and rationale for determining the orientation of the unknown analyzers.  

 

~~2. What were the best basis and state to determine this? 

 

~~3. In which simulation was the analyzer off axis (i.e., not x, y, or z)?  If you were not able to determine the orientation of this analyzer, here is a hint, it is in the xy plane.  As a consequence,  you should begin by writing SΘ = cos(Θ) Sx + sin(Θ) Sy and then determine the eigenvectors and eigenvalues of this matrix.
