$consider3dipoles

$consider3dipoles is the command to decide if the emission light is a pure dipole source and the ratio of Px, Py, and Pz.

$consider3dipoles
Px Py Pz

Px, Py, Pz are the ratio of Px, Py, Pz dipole. They should be positive values.
After 3 values are set, the possibility to emit x-polarized diople Px would be

$R_{p}x=\frac{Px}{Px+Py+Pz}$
