WDS 16540-4143 SNA 50 AB (HD 152218) : NOTES

discov_num	notes	refcode
SNA 50	The primary is V1294 Sco, a detached Algol-type eclipsing binary and	Sna2008b
	SB2, with a period of 5.8d (Sana et al. 2008).	Sna2014
HD 152218	NGC 6231 #2. The classification is from the UV tomographic analysis	Pny1993
	of Penny et al. (1993). A new orbit by Stickland et al. (1997) yields	Stc1997
	a period of 5.604 d.	Msn1998a
