uvcombine

Tools for combining high-resolution images with missing large angular scales (Fourier-domain short-spacings) with low-resolution images containing the short/zero spacing.

The modules can be installed like a normal python project:

python setup.py install

If you have difficulty, refer to astropy's installation documentation, since we use the same infrastructure.

The main code is incompletely documented in uvcombine/uvcombine.py.

A good starting point to understanding what the code is doing and what uncertainties are involved in combination is this notebook: https://github.com/radio-astro-tools/uvcombine/blob/master/examples/FeatheringTests.ipynb
