An example of the spectropolarimetric signatures of the sample. The top half of the figure presents the spectropolarimetric PA, the percentage polarisation, and the Stokes intensity spectra centred upon Hα. The data are binned to a constant polarisation error, which is stated in the plots. The solid red line is the un-binned line profile. The QU diagrams of the signatures are displayed in the lower half of the figure. The solid lines mark the direction of the intrinsic polarisation.
