BSO 7	B is CPD-62@2205.
	BSO 7B is the optical companion of HD 101436 (Lindroos 1985).	Lnd1985
	Both stars were observed and appeared to be single.	Msn1998a
	Additional diverse radial velocities for HD 101413 are reported by	Wes1965
	Thackeray & Wesselink (1965) and Conti et al. (1977).	Cti1977
SNA 28	Ba,Bb: HD 101413 is a 3 to 6-month period SB2 (Sana et al. 2011), with	Sna2011a
	the spectroscopic companion being a likely mid-B star. The 54mas
	companion is too far away and too bright to be associated with the
	spectroscopic companion.	Sna2014
