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.
