GrismThetaGrismTheta
-
Angle between normal to detector plane and reference ray
- Description:
- This attribute gives the angle of incidence of light of the
reference wavelength (given by attribute GrismWaveRGrismWaveR) onto the
detector. Specifically, it holds the angle (in radians) between
the normal to the detector plane and an incident ray at the reference
wavelength. The default value is 0.0.
- Type:
- Double precision.
