Notes. Stokes V flux (circular polarisation) of QS Vir and corresponding polarisation fractions. Error values are the RMS of the background. The polarisation direction, left circularly polarised (LCP) or right circularly polarised (RCP), is included for flux fits above 3 × RMS. Fits below this limit were replaced with 3 × RMS upper limits.
