All Implemented Interfaces:

Serializable, PickConnected

public class NoDaughterAvailable
extends ErrorEvent
implements PickConnected

An error signaling that a starting from a parent target, the current observational conditions do not allow the selection of a daugther class. This error is produced after a parent target (e.g. a calibration target) has been picked, but out of the list of calibration stars none is available at the moment. This error can be handled like any other error occuring during the observing sequence, i.e. it may block or delay the calibration target.
