Notes. The spectral type and photometry is taken from Vink et al. (2023). We also include revised spectral types based on the XShootu dataset from Crowther (in prep.). All objects have been observed using STIS. Here we show which grating was used and whether it was also observed using Far Ultraviolet Spectroscopic Explorer (FUSE).
