EWs, FWHMs and RVs of main lines in the spectrum of the new WR star BAT99 3a (star 1). For EWs and RVs, we give their mean values derived from both Gemini spectra, while for measurements of FWHMs, we used the second spectrum alone owing to its better quality.

^aNote that some of the starred EWs and FWHMs are significantly affected because of the binary nature of BAT99 3a. The negative (positive) EWs correspond to emission (absorption) lines originating from the WR (O) component of BAT99 3a (see the text for details).
