Improved test model for VFTS 457 (O3.5 If*/WN7) relative to Fig. E.26. The N abundance is twice that of our enriched models. In addition, the model differs by having a lower log g (3.5 dex) and by starting the clumping in the wind velocity law at 10 km s^-1. Ṁ was reduced as well to compensate the line strength increases as a result of the lower log g. The difference in Ṁ is less than 0.1 dex.
