qspec.analyze.ellipse2d  (  x ,  y ,  scale_x ,  scale_y ,  phi ,  corr  )[source]

Parameters:

xarray_like

The x-component of the position of the ellipse.

yarray_like

The y-component of the position of the ellipse.

scale_xarray_like

The amplitude of the x-component.

scale_yarray_like

The amplitude of the y-component.

phiarray_like

The angle between the vector to the point on the ellipse and the x-axis.

corrarray_like

The correlation coefficient between the x and y data.

Returns:

out(ndarray, ndarray)

A point on an ellipse in 2d-space with amplitudes 'x', 'y' and correlation 'corr' between x- and y-component.
