Direct Known Subclasses:

AveragePinhole.FullPinhole, ModelDrift.PinholeDrift, ModelShift.PinholeShift

Enclosing class:

AbstractPinholeModel

public abstract static class AbstractPinholeModel.AbstractPinholeFits
extends AbstractFitsImageModel

This is the data model that somehow describes the star plus pinhole. At least the relative shift of the star to the pinhole plus the star flux/instensity and its FWHM must be modelled, but more sophisticated methods might also include pinhole drift/size etc. modelling.

Method Summary

Modifier and Type	Method and Description
protected Vector3D	applyBackground(double back, double backerr) We apply the measured background and its error in the sense that we use a gain of one and a default sigma of three.
protected Vector3D	applyBackground(double back, double backerr, double sigma, double gain) We apply the measured background and its error and use the returned photon statistics array as our sigma statistic.
abstract VectorG	getFirstModel() Returns a first estimate.
abstract VectorG	getFirstStep() Returns step size of the first model for simplex use.
abstract double[]	getStarModel(VectorG solution) Returns the model of the star as it would have been seen without the pinhole.

Method Detail

applyBackground

protected Vector3D applyBackground(double back,
                                   double backerr)

We apply the measured background and its error in the sense that we use a gain of one and a default sigma of three.

Parameters:

back -

backerr -

Returns:

applyBackground

protected Vector3D applyBackground(double back,
                                   double backerr,
                                   double sigma,
                                   double gain)

We apply the measured background and its error and use the returned photon statistics array as our sigma statistic.

Parameters:

back -

backerr -

sigma -

gain -

Returns:

getFirstModel

public abstract VectorG getFirstModel()

Returns a first estimate.

getFirstStep

public abstract VectorG getFirstStep()

Returns step size of the first model for simplex use. Might return null if only used with Levenberg Marquardt.

getStarModel

public abstract double[] getStarModel(VectorG solution)

Returns the model of the star as it would have been seen without the pinhole.
