What do these numbers represent, are they the XYZ coordinated? I believe they are rectangular coordinates as there are six points. I checked the documentation, but I am still confused about how one defines/calculates these points. 

My goal is to write a script that can automatically fill in the orientations for multiple composite layers. 

For example, 

*Orientation, name=Ori-Phase1_1
-1.000000e+00, -1.224647e-16, 6.123234e-17, 6.123234e-17, -1.000000e+00, 6.123234e-17
1, 0.

Thanks
