Specifies the refraction model to be used in computing this VisibilitySegment. Most of the available refraction models use the VisibilitySegment.RefractionFrequency value as an input. Descriptions of the models and a list of references are provided in the Help File.
The "Analytic - Chapman" and "Analytic - TRORD" models are only allowed when the observing object is a GroundStation.
The "Analytic - TRORD" model uses the local-mean coefficients for each month specified by the GroundStation.RefractivityNs property of the observing GroundStation.
The "Analytic - TRORD" and "Numeric - Exponential" models do not use the VisibilitySegment.RefractionFrequency setting.
The following refraction models are available. Note that these models are used only for calculating refraction through the Earth's atmosphere. Currently, refraction is not modeled for any other celestial bodies.
