discov_num notes refcode
CST 8 AB: IR sources in rho Oph cloud.
A component = V2247 Oph = SR 12 = HBC 263 = ROX 21.
1986.4: 0.45 - 0.18 flux ratio in J band, 1.00 - 0.35 in H band Smn1987
ALO 7 AC: Kuzuhara et al. (2011) confirm that the C component is a member of Kuz2011
the rho Oph star-forming region and is physically associated with the
AB pair. The mass of C is estimated at 14 +7/-8 Mjup.
