Sigma

Type:Vector<float>
Range:[v_1, …, v_2]
Default:-/-
Appearance:optional

This parameter specifies the Bloch vector \pvec{k}_{\mathrm{B}} of the BlochFamily. It is determined from the \sigma-coordinates in the pupil plane (see Plane Wave) of a representative of the family. By default Sigma = [0 0] is used.
