| Abstract: |
The Polarisation Sky Survey of the Universe's Magnetism will measure
Faraday rotation towards three million distant galaxies, dramatically
improving our understanding of cosmic magnetism. Polarisation
observations are multi-dimensional and require advanced techniques to
tease out reliable scientific results. Here we present a prototype
analysis pipeline intended to facilitate quality control during
observations and create a robust and timely polarisation
catalogue. The software makes use of techniques such as rotation
measure synthesis and Bayesian model fitting to characterise
polarisation properties. The pipeline code is freely available online
and is flexible enough to be used with data from many telescopes. |
