Reality of the apparent second-component circular-polarisation preference

Determine whether the apparent preference for circular polarisation in the second component of multi-component fast radio bursts represents a genuine population characteristic or is produced by the small number of currently available bursts.

Background

The paper identifies an apparent trend in which circular polarisation occurs preferentially in the second component of several multi-component CRAFT bursts, while noting that the trend is not universal and that repeaters exhibit substantial burst-to-burst polarimetric variability. The authors therefore leave unresolved whether this pattern reflects a physical property of the fast-radio-burst population or a sampling effect caused by the limited number of observed events.
