uvcombine provides tools for combining high-resolution images with missing large angular scales (Fourier-domain short-spacings) with low-resolution images containing the short/zero spacing, including:
- Feathering two images
- Feathering two cubes (including for large cubes using spectral-cube's dask implementation)
- uv-overlap consistency tests and measuring the single dish flux scaling factor.
See the documentation for more information. Worked notebook examples of the uvcombine functionality can be found in the examples directory.
Install the latest release from PyPI with:
pip install uvcombine
Example notebooks under examples/ are kept free of cell outputs on main so
diffs stay reviewable. This is enforced by a pre-commit hook (nbstripout) plus a CI check that fails if a notebook
with outputs is pushed. To set up the hook locally:
pip install -e ".[notebooks]" pre-commit install
Notebooks with their outputs executed are kept on the with-output branch
instead; it is refreshed manually (not by CI) whenever an example notebook changes.
This package is part of the radio-astro-tools project. See radio-astro-tools for more information.
