Top panels: phase-folded, continuum-normalised and subtracted trailed spectra of four of the lines from the Magellan data. Middle and bottom panels: equivalent Doppler maps and fits. White crosses mark the centre of a disc. At phase 1, the HeII 4859 data show a dark feature, especially on the blueshifted side, and slightly delayed in phase near zero velocity, which is the signature of an eclipse of the disc.
