Options

If the debug option is specified the X,Y,Z coordinates of the earth and the asteroid are printed out as well as other parameters, such as the distance from Earth (Delta), the distance from the sun (r), the solar angle (beta). All distances are in a.u. and angles in degrees. All XYZ coordinates are heliocentric.

If the rates option is specified the the position of the asteroid is calculated as well as the position one day later and the rates are calculated. A line similar to:

ra=-0.0074 dec=0.0022

Where the ra and dec track rates are in arc-seconds per second.
