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.

Constructor Summary

Position(double l, double b)
Define a position object in the standard (J2000) frame

Position(double l, double b, java.lang.String frame)
Define a position object used a specified frame

Method Summary

double[]	getPosition() Get the position in the standard (J2000) frame
double[]	getPosition(java.lang.String frame) Get the position in a specified frame
static void	main(java.lang.String[] args) Test the Position class
