Notes: {\it ``em-lines''} reefers to stars with emission lines in their optical spectra. {\it ``CW''} notes those binaries with a colliding wind region. {\it ``Open''} reefers to those long period binaries, i.e. with well-separated components. Components~(A)$-$(C) refer to system components sorted according to mass decrease.
