Ionospheric Faraday rotation prediction and correction for radio astronomy polarization cubes.
Project description
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. Note that there are significant changes in Version 1.1, which are documented there.
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.
