The spectrum of VFTS 422 (O4 III(f)) shows the characteristic of a SB1. The temperature is based on the lines N iii λ4634/4640 and N iv λ4058. The He i λ4471 line could not be used due to the strong nebular contamination. Ṁ is based on the line shape of He ii λ4686 and is a bit too high in the model. N-abundance is between normal and enriched.
