Our article ‘Circular polarimetry of suspect wind-accreting magnetic pre-polars’, published in Monthly Notices of the Royal Astronomical Society, 2022, Volume 513, Issue 3, pp. 3858–3870, contained a faulty figure. Due to an error in a plotting routine, the original fig. 10 is flawed, as the shown X-axis does not correspond to the displayed figure. The correct fig. 10 is included here (as Fig. 1). This has no effect on the text itself or any of the conclusions.

The cyclotron emission spectra from constant low temperature (1 keV) and (logΛ = 5) ‘slab’ models as a function of the magnetic field strength. The locations of g and r passbands are shown with vertical dashed lines.
