Combined FLAMES-Medusa spectrum of VFTS 682, a newly discovered Wolf-Rayet star. Identified lines are, from left-to-right by species: Hδ, Hγ, and Hβ (each with super-imposed nebular emission); He I λλ4026, 4471, 4922, 5015 (each from nebular emission); He II λλ4200, 4542, 4686; N IV λ4058; N V λλ4520, 4604-4620, 4944; and the [O III] nebular lines at λλ4363, 4959, 5007.

Combined FLAMES-ARGUS spectrum of VFTS 1003, a newly discovered B[e]-type star. There appears to be weak stellar absorption at He I λλ4009, 4026, 4388, 4471, combined with weak nebular emission components, particularly at λ4471. In addition to the Balmer lines, the identified lines are [S II] λ4069; [O III] λ4363; Fe II λλ4173, 4179, 4233, 4303, 4352, 4385, 4481, 4491, 4508, 4515, 4520-23, 4549, 4556; [Fe II] λλ4244, 4277, 4287, 4358-59, 4414-16.

FLAMES-Giraffe spectroscopy of ten candidate YSOs from Gruendl & Chu (2009), as summarised in Table 4. Strong nebular lines have been truncated as indicated. The He II lines identifed in VFTS 500 (a double-lined spectroscopic binary) are: λλ4200, 4542, 4686; He I lines identified in VFTS 631 are: λλ4009, 4026, 4144, 4388, 4471, 4713.
