Detailed view of He II 4686 Å and He I 4713 Å for the new magnetic He-sdOs. The merged RSS spectra (black) are best matched by Zeeman-split models (red). Models with the best-fit atmospheric parameters but zero magnetic field (dashed red) are excluded even if υ sin i is allowed to vary (blue). At zero field strength, the best-fit υ sin i would equal 190, 180, and 130 km s⁻¹ for J1233–6749, J1256–5753, and J1444–6744, respectively.
