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 |
