Notes.

^(a)

Position from fitting the source in polarized intensity.

^(b)

Observed intensity at the pixel closest to the fitted position.

^(c)

Polarized intensity, found by fitting a 3D Gaussian to the source.

^(d)

Rotation measure, found by fitting a 3D Gaussian to the source. The ionospheric Faraday rotation correction introduces an additional systematic error of about 0.1–0.3 rad m^-2.

^(e)

Rotation measure from the catalogue of Taylor et al. (2009).

^(f)

These sources are at the position of WNB 0313+683.
