public class AltAzVelocity
extends RaDeParser

A class to calculate both, the velocity in altitude and azimuth, for a given target at a given time. Additionally, current image rotation and the revolution of the image in Nasmith foci are calculated. The target is supplied either with -ra, -rah, or -ras, declination with -de -des, time, if any, is given with -t and a parsable date.
