1. Offline Fine PFB: The documentation for the offline fine PFB is found here. The FINEPFB filter should be used (as of this writing, 4 Nov 2021, this is the only available option).
2. Offline Correlator: The documentation for the offline correlator is found here. On Garrawarla, there are two versions available, which differ by the integration time set by the underlying xGPU dependency. The offline_correlator/master module uses a "base" integration time of 0.1 secs, while the offline_correlator/millisecond module uses 0.02 secs. For the purposes of generating calibration solutions, the master version should be used. This step can also be achieved using the legacy pipeline, documented here.
3. RTS: Currently, the only documentation is found on the legacy page.

...

The legacy page describes one set of tools for visualising the RTS solutions, and these can be applied equally well to the RTS solutions produced by any of the methods above. However, VCSBeam (>= v2.18) now contains tools for visualising the solutions in an alternative, complementary way.

1. Use mwa_plot_calibration to generate an ASCII file containing the calibration solution in a way that can be readily plotted.
2. Use plotUse plot_calibration.py to generate the plots themselves.

Example usage

$ mwa_plot_calibration -m /PATH/TO/1240826896_metafits_ppds.fits -c /PATH/TO/1240827912.metafits -C /PATH/TO/RTS/OUTPUT -N 24 -R NONE -U 0,0 -X > solution.txt
$ /PATH/TO/plot_calibration.py solution.txt
