ln_rect_posn(3)

NAME
ln_rect_posn - Rectangular coordinates.

SYNOPSIS

#include <ln_types.h>

  Data Fields
double X
double Y
double Z

Detailed Description

Rectangular coordinates. Rectangular Coordinates of a body. These coordinates can be either geocentric or heliocentric.

A heliocentric position is an objects position relative to the centre of the Sun. A geocentric position is an objects position relative to the centre of the Earth.

Position is in units of AU for planets and in units of km for the Moon.

Examples
asteroid.c, comet.c, and lunar.c.
