Constructor	Description
DSS(double plate_ra, double plate_dec, double x_pixel_size, double y_pixel_size, double plate_scale, double[] ppo_coeff, double[] x_coeff, double[] y_coeff)

Method Summary

Modifier and Type	Method	Description
String	getDescription()	What does this object do?
String	getName()	Get the name of this component
Distorter	inverse()	The inverse Distorter (i.e., the undistorter) uses much of the same machinery, so we generate it as a inner class of the distorter.
boolean	isInverse(Transformer t)	Is this the inverse of another distorter?
protected boolean	preserves()
void	transform(double[] x, double[] y)	Convert a single point where the output vector is supplied.

Method Detail

transform

public void transform(double[] x,
                      double[] y)

Description copied from class: Transformer

Convert a single point where the output vector is supplied.

Specified by:

transform in class Transformer

Parameters:

x - The input vector.

y - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.

getName

public String getName()

Get the name of this component

Specified by:

getName in interface Component

Specified by:

getName in class Distorter

getDescription

public String getDescription()

Description copied from class: Distorter

What does this object do?

Specified by:

getDescription in interface Component

Specified by:

getDescription in class Distorter

preserves

protected boolean preserves()

inverse

public Distorter inverse()

The inverse Distorter (i.e., the undistorter) uses much of the same machinery, so we generate it as a inner class of the distorter.

Specified by:

inverse in class Distorter

isInverse

public boolean isInverse(Transformer t)

Is this the inverse of another distorter?

Specified by:

isInverse in class Transformer
