◆ emissionAngle()

Computes and returns emission angle, in degrees, given the observer position.

Emission Angle: The angle between the surface normal vector at the intersection point and the vector from the intersection point to the observer (usually the spacecraft). The emission angle varies from 0 degrees when the observer is viewing the sub-spacecraft point (nadir viewing) to 90 degrees when the intercept is tangent to the surface of the target body. Thus, higher values of emission angle indicate more oblique viewing of the target.

Parameters

observerBodyFixedPosition Three dimensional position of the observer, in the coordinate system of the target body.
