Detailed Description

A series of connected line segments in the sky, composed of SkyPoints at its vertices.

SkyLines are used for constellation lines and boundaries, the coordinate grid, and the equator, ecliptic and horizon.

Note

the SkyLine segments are always straight lines, they are not Great Circle segments joining the two endpoints. Therefore, line segments that need to follow great circles must be approximated with many short SkyLine segments.
