Ionospheric Faraday rotation prediction and correction for radio astronomy polarization cubes.

Ionospheric Faraday rotation corrections.

Scripts for calculating and applying ionospheric Faraday rotation corrections for radio polarization data, primarily time-independent corrections.

Full documentation can be found here.

The core underlying tool is RMextract which calculates the time-dependent ionospheric Faraday rotation. This script uses that to generate the time-integrated correction for a given observation.

This is being written for the POSSUM pipeline, but with hopes that it can be general enough to apply to other data sets.
