... stars[*]
Actually one star less, as we believe that WR 109 (classified in the WR catalog as WN5h+?) is erroneously counted here as a WN star. The typical brightness of a WN star would imply an implausible large distance ($D\!M$ = 17.4 mag), placing it beyond our Galaxy. From the binary period and the optical flickering, it has been concluded already (Steiner et al. 1988, 1999; Steiner & Diaz 1998) that WR 109 is a cataclysmic variable (CV).
