Class Position

java.lang.Object

skyview.geometry.Position

public class Position
extends java.lang.Object

This class represents a position in the sky. This class is used to pass a position that may be represented in different frames in different parts of a program. However since it creates CoordinateSystem objects for each transformation it should not be used to do coordinate transformations for large arrays of positions.
