astrowisp.piecewise_bicubic_psf_map module

Class Inheritance Diagram

A wrapper class for working with PSF/PRF maps from the C/C++ library.

class astrowisp.piecewise_bicubic_psf_map.PiecewiseBicubicPSFMap(star_shape_map_tree)

Bases: object

Provide convenient python interface to shape fitting results.

__call__(term_values)

Evaluate the map for a given set of terms.

Parameters:

term_values – The terms that PSF parameters depend on evaluated for the particular source we wish to know the PSF of.

Returns:

The PSF/PRF the map predicts for the given arguments.

Return type:

PSF

__del__()

Delete any objects allocated by the library.

__init__(star_shape_map_tree)

Prepare to query the map generated by a star shape fit.

Parameters:

star_shape_map_tree (IOTree) – The result returned by calling FitStarShape.fit().

Returns:

None
