All Implemented Interfaces:

Cloneable, Initializable, LocalizedSupplying, PropertySupplying, ResourceSupplying, VectorFunction

Enclosing class:

WcsProjection

public static class WcsProjection.VariablePixelProjection
extends WcsProjection.LinearPixelProjection

It turned out, that the quality of the WCS solution is highly dependant on the correct position of the native pole, rj. This class solves also for this parameters. It should be done probably only once, then these values should be frozen.

Constructor Summary

WcsProjection.VariablePixelProjection()
We only allow full variations in the transformation matrix.

WcsProjection.VariablePixelProjection(Map<String,String> u2f)
We only allow full variations in the transformation matrix.

Method Summary

VectorG	estimateParameters(nom.tam.fits.Header h) We refer to the parental parsing methods, but sneak in on the returned parameters, adding the center of projection at the end of the list.
VectorG	estimateParameterScales(VectorG start) The parameter scales are wrong, we have a translatory matrix and a rotation.
VectorG	getParameters() We query the cij from the parent and add the projection center at the end
void	setParameters(VectorG vv) The first four parameters are the cij, then we have the projection center.

Constructor Detail

WcsProjection.VariablePixelProjection

public WcsProjection.VariablePixelProjection()

We only allow full variations in the transformation matrix.

WcsProjection.VariablePixelProjection

public WcsProjection.VariablePixelProjection(Map<String,String> u2f)

We only allow full variations in the transformation matrix.

Method Detail

setParameters

public void setParameters(VectorG vv)

The first four parameters are the cij, then we have the projection center. This is set in the parent as rj

Overrides:

setParameters in class WcsProjection.LinearPixelProjection

getParameters

public VectorG getParameters()

We query the cij from the parent and add the projection center at the end

Overrides:

getParameters in class WcsProjection.LinearPixelProjection

estimateParameters

public VectorG estimateParameters(nom.tam.fits.Header h)
                           throws nom.tam.fits.HeaderCardException

We refer to the parental parsing methods, but sneak in on the returned parameters, adding the center of projection at the end of the list.

Overrides:

estimateParameters in class WcsProjection.LinearPixelProjection

Throws:

nom.tam.fits.HeaderCardException

estimateParameterScales

public VectorG estimateParameterScales(VectorG start)

The parameter scales are wrong, we have a translatory matrix and a rotation.

Overrides:

estimateParameterScales in class WcsProjection
