G9V

Garrison94 does not list a G9V anchor standard, and MK73 does not list
a G9V dagger standard. 

There are no "good" standards for the G9V subtype. 

Keenan84 does not list G9 as a full subtype like G8 and K0, and "other
possible subdivisions are utilized only for interpolation whenever we
think that we can classify accurately enough to justify their
use. Thus when we call a star G3 we mean only that it is closer to G2
than to G5."

The two Gray et al. G9V stars with identical median B-I colors are HIP
21327 and HIP 29761. I discuss them below.

  active star in Mt. Wilson survey, and discussed extensively in
  Henry95(1995AJ....110.2926H, Sec. 6.16). Henry95 tabulates published

  (1999A&A...347..249M) also wrote separate paper on the star's

  6th brightest "G9V" in Bright Star Catalog, but probably the only
  real dwarf among them. WDS 0.2" equal brightness SB2 binary whose
  glorious history is told in Griffin82^2 (1982Obs...102..217G;
  P=984+-7d, estimates masses 1.0 and 0.9 Msun).  Orbit has semi-major
  axis 0.126" but was split with "eyepiece interferometer" by
  Finsen59. 43" pair with L8+T0 brown dwarf binary GJ 337CD = 2MASS
  J09121469+1459396.  Mv=4.95(xHIP). V=6.500+-0.013(Mermilliod91),
  V(A)=7.20(WDS), V(B)=7.20(WDS), B-V=0.731+-0.006(Mermilliod91). For
  delta(V)=0.0(WDS) => V(A)=V(B)=7.25.
  plx=49.1493+-0.3467mas(GaiaDR2) => Mv(A)=Mv(B)=5.71+-0.02.

   Just two classifications as G9V. V=7.060(Mermilliod91),
   B-V=0.780(Mermilliod91), U-B=0.380(Mermilliod91).  Pair with HD
   116443 (26" away), which is K2V (Gray03) or K1V (Abt08).

 *K0/1III: Houk99

  2nd brightest G9V in Bright Star Catalog (although brightest is an
  RS CVn system), but spectroscopic loggs are consistent with giant.
  PASTEL: <Teff>=4929K(N=4), <logg>=3.23(N=4), <[Fe/H]>=+0.06(N=4).

 *K0/1III: Houk99

  3rd brightest "G9V" in Bright Star Catalog, but like the brighter
  two, also appears to be evolved (giant).  Binary or triple in WDS,
  with closest companion B at 13.5" separation (mag=13.5).  PASTEL:
