Constructor Summary

FocusSpindleFit.CorkScrew()

Method Summary

int	dimension() If we also fit for the lead, we return nine, otherwise eight.
Point2D	getModelPoint(double f, VectorG params) We evaluate the formular from above, using the pre-set values of the pixel and focus positions.

Method Detail

dimension

public int dimension()

If we also fit for the lead, we return nine, otherwise eight.

getModelPoint

public Point2D getModelPoint(double f,
                             VectorG params)

We evaluate the formular from above, using the pre-set values of the pixel and focus positions. The following order is assumed:

constant position x, x_0

constant position y, y_0<

linear with focus in x, v_x

linear with focus in y, v_y

pixel semi-major axis a of ellipsoid

numerical excentricity e of ellipsoid

tilt angle of ellipsoid, θ_0

offset of polar angle phi, φ_0

If no lead is set, this is used, otherwise ignored
