OB eclipsing Stars in the 3 OB categories and corresponding statistics.
N_i:	OBMS (%)	OBe (%)	OBSG (%)	$N_{\rm tot}$
Ecl. binaries	89 ( $73\pm10$ )	7( $6\pm5$ )	26 ( $21\pm9$ )	122
OB_i,e vs. tot. OB	$4\pm1$	$0.3\pm0.3$	$1\pm0.5$	$5.3\pm1.2$
OB_i,e vs. tot. OB_i	$6\pm2$	$3\pm3$	$4\pm2$
OB_i,e vs. OB_i,v	$28\pm6$	$3.9\pm3.8$	$10\pm5$
Not included	5	0	0	5
Total category	94 ( $74\pm10$ )	7 ( $6\pm5$ )	26 ( $20\pm9$ )	127

OB_i corresponds to the 3 intrinsic categories, i being OBMS, OBe or OBSG. The index v stands for ``variable'' (above $T_{\rm h}$ ). The line ``Not included'' refers to the stars that were not included in the analysis because of too many flagged points, or below $T_{\rm h}$ .
