class glue.plugins.wcs_autolinking.wcs_autolinking.WCSLink(data1=None, data2=None, cids1=None, cids2=None)[source]#

A collection of links that link the pixel components of two datasets via WCS transformations.

Methods Summary

as_affine_link([n_samples, tolerance])

Approximate the link as an affine transformation which can, if the approximation is good, result in significant performance improvements.

as_affine_link(n_samples=1000, tolerance=1)[source]#

Approximate the link as an affine transformation which can, if the approximation is good, result in significant performance improvements.

For now this will only work for datasets in which two pixel coordinates are linked.

The deviation to be compared to the tolerance is measured in the frame of reference of the second dataset.
