fitswcs_transform_from_model

jwst.assign_wcs.pointing.fitswcs_transform_from_model(wcsinfo, wavetable=None)

Create a WCS object using from datamodel.meta.wcsinfo.

Transforms assume 0-based coordinates.

Parameters:

wcsinfodict-like

model.meta.wcsinfo structure.

wavetableTable or None, optional

A table with wavelength values. If None, a linear transformation will be used.

Returns:

transformModel

WCS forward transform - from pixel to world coordinates.
