Constructor Detail

RaActual

public RaActual(Map prop)

Constructs a new global representing the actual object's ra.

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

Specified by:

getForTarget in interface TargetDependingParameter

Overrides:

getForTarget in class RaTarget

Returns:

A Double holding the target star's right ascension.

getValue

public Number getValue()
