Constructor Detail

TrackVelocity

public TrackVelocity(Map info)

Constructs a new airmass target object. Note that this global can only function correctly after the tau and dec of the target and the teide latitude have been registered.

Method Detail

rescanned

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

As any parameter depending instance we fail if the parameter we depend on is now a different one.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

setValue

public Number setValue(Number val)
                throws UnsupportedOperationException

Sets the airmass of the actual target. This is a read-only variable, therefore this method throws an UnsupportedOperationException.

Specified by:

setValue in interface Value

Throws:

UnsupportedOperationException

getForTarget

public Number getForTarget(TargetDefinition star)

Gets the declination of the target star.

Specified by:

getForTarget in interface TargetDependingValue

Specified by:

getForTarget in interface TargetDependingParameter

Returns:

A Double holding the target star's declination.

getValue

public Number getValue()

Returns the target's actual airmass, wrapped into a Double. Note that this method returns null if either of the globals denoting the tau, dec of the target or the latitude is missing.

Specified by:

getValue in interface Value

registerParameter

public void registerParameter(Parameter what)

Registers the required additional globals for the tracking velocity. For this parameter, the tracking velocity in altitude and azimuth is required.

Specified by:

registerParameter in interface ParameterDepending

registerTarget

public void registerTarget(TargetDefinition star)

Registers a star to this parameter. The target definition is directly passed to the azvel and altvel reference of this parameter. Note that this will set the target in the additional parameter, too.

Specified by:

registerTarget in interface TargetDepending

calculate

private Double calculate(Number azv,
                         Number altv)

Calculates the airmass using the hour angle and the declination of the target. The latitude of the site must be registered first.
