Notes. The other samples are the B-type star binaries in 30 Doradus (BBC) and the B-type stars in Cygnus OB2 (K14). The spectral sub-type range is given in the brackets next to the ID of each sample. D is the Kuiper D number and dpp is the probability that a value as large as D would occur if data was drawn from the given distribution. The spectral sub-type range is given in the brackets next to the ID of each sample.
