public class DerotatorOffset
extends AbstractTargetValue
implements ParameterDepending, Reloadable

A derotator offset is calculated such that Wifsip always points approximately to the ground, but at the same time keeping the CCD geometry fixed.

Field Detail

KEY_IMAGEROTATION

public static final String KEY_IMAGEROTATION

The name of the image rotation to use.

Constant Field Values

DEFNAME

public static final String DEFNAME

Default name of the parameter .

See Also:

Constant Field Values

DEFIMAGEROTATION

private static final String DEFIMAGEROTATION

Default name of the nasmith image rotation.

See Also:

Constant Field Values

rot

private ImageRotation rot

The image rotation, degrees.

Constructor Detail

DerotatorOffset

public DerotatorOffset(Map<String,String> info)

Constructs a image rotation 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

registerParameter

public void registerParameter(Parameter alt)

Register the altitude of the target.

Specified by:

registerParameter in interface ParameterDepending

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

registerTarget

public void registerTarget(TargetDefinition star)

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

Specified by:

registerTarget in interface TargetDepending

offset

public static double offset(double imrot)

Calculates an offset to have the lower half of wifsip pointing down.
