$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. <br> After 3 values are set, the possibility to emit x-polarized diople Px would be
 
 <math> R_px = \frac{Px}{Px+Py+Pz} </math>
