VFTS 1001 (WN6(h)): The temperature is based on the lines He i λ4471, N iii λ4634/4640, N iv λ4058, N v λ4604/4620. Ṁ and He-abundance are based on the lines He ii λ4686, Hα, He ii 2.19 μm, and 
. Ṁ is slightly too low for the best fitting model. The model suggests a He-abundance of 85%. (Second panel: HST/FOS, third panel: ARGUS. The ARGUS data were only approximately normalised as there prime use was the investigations of RV/LPV variations).
