WCSLink

class glue.plugins.wcs_autolinking.wcs_autolinking.WCSLink(data1=None, data2=None, cids1=None, cids2=None)

Bases: MultiLink

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

Attributes Summary

cid_independent
description	str(object='') -> str str(bytes_or_buffer[, encoding[, errors]]) -> str
display

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.

display = 'WCS link'

Methods Documentation

as_affine_link(n_samples=1000, tolerance=1)

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.
