All Implemented Interfaces:

Serializable, TargetDependingCommand, EnvironmentCommand

public class FollowRoof
extends CommandEvent
implements EnvironmentCommand, TargetDependingCommand

The move telescope command. It takes dom-elements of type star and scans its general section for the ra, dec, equinox, and proper motions to derive the actual position of the target star from it. The targets ra and dec, both in degrees in the actual equinox, are placed onto the command line.
