Class Inheritance Diagram

Define the BipolynomialPSFPiece class.

class astrowisp.fake_image.bipolynomial_psf_piece.BipolynomialPSFPiece(coefficients)

Bases: PSFPiece

Class for PSF pieces over which the PSF is a bi-polynomial function.

__call__(x, y)

Evaluate the bi-cubic polynomial at the given position.

__init__(coefficients)

Initialize a bi-cubic PSF piece with a set of coefficients.

Parameters:

coefficients – The bi-cubic polynomial coefficients. Should be a two-index structure with the first index beige y power of the term and the second index the x-power.

Returns:

None
