discov_num notes refcode
HJ 4495 HIP 59021. Both components A,B are above the MS by 1.5 mag. Wrong Tok2011a
parallax? The photometric parallax would be ~40 mas. See Holmberg et Nrd2009
al. (2009) for improved distance. Planet host? Nid2002
AB: B is SB2, P=148.26d. A is SB and possible astrometric binary, Tok2010c
although not resolved with NICI (Tokovinin et al. 2010) Tok2014d
