Notes. TWUIN stars (i.e., CHB objects) are typically assigned to some O-type subclass; a “< ” sign indicates that a model is consistent with earlier classes as well. For WR stars, the spectrum may be consistent with more than one subclass; we give the secondary classification (as defined in Table 3 of Crowther & Hadfield 2006) in square brackets. See also the text and Appendix A.
