Description
Determines the entry time, exit time, and duration of a Spacecraft's pass through the shadow of a central body. Events are reported for annular shadow conditions only.
The shadow times are determined using a conical shadow. The three regions of the Spacecraft's central body's shadow, umbra, penumbra, and annular, are shown in the diagram below. AnnularShadowTimes reports events when the Spacecraft is in the annual portion of it's central body's shadow.
