LR02 (upper) and LR03 (lower) spectra for VFTS 399 encompassing the N iii multiplet near 4515Å. Also shown are theoretical spectra with nitrogen abundances of 7.62 dex (red, dash) and 7.92 (blue, dot-dash), convolved with an appropriate broadening function. The absorption near 4541 Å is due to He ii.
