G1V

No G1V dagger type according to Garrison94.

HD 27836 is a G1V dagger type in MK73, primary standard of Houk, 
but not mentioned in Garrison94. 

MorganAbt73 lists HD 27836 and Bet CVn as their G1V standards.

Skiff08 lists five G1V (and variants) MK standards: HD 27836 (G1V;
MK73), HD 10307 (G1V; Keenan89), HD 20807 (G1V; Keenan89), HD 115043
(G1Va;Keenan89), HD 142267 (Keenan89; G1V Fe-1).

Morgan65 classify 5 Hyads as G1V: HD 27836, 27859, 28344, 28992, &
29310.

Gray01/03/06 list 66 nearby G1V stars. Median HIP colors:
<B-V>(G1V) = 0.627 (+-0.003 sem, +-0.019 stdev; N=66)
<V-I>(G1V) = 0.692 (+-0.001 sem, +-0.015 stdev; N=66)

# No standard
Morgan65, Cowley76, Keenan85, and Corbally86 do not list G1V standards

# primary standard
HD 27836 = HIP 20553 = Cl Melotte 25 50 (Hyad)
  G1V: HoukStandard,MK73,MorganAbt73
  G0V CaII(e): Gray01
  comments: 0.3" binary, delta(V) = 3 mag
  B-V(Merm91)  = 0.604+-0.009
  B-V(HIP)=0.604, Vmag=7.58, Mv=4.32, dMv=-0.18, par=22.3+-1.5 mas
  so B-V is representative of the G1V class 
  Ks = 6.007 +- 0.009 (2MASS)
  V  = 7.645 (HIP; CCDM split of V=7.58, delHp=3.021mag)
  V-Ks = 1.638 mag

  Jaschek64 split between G1V and G2V (7 vs. 7)
  Ks = 5.334+-0.009 (2MASS)
  V-Ks = 1.486 mag
  B-V(HIP) = 0.602, Vmag=6.82, Mv=4.77, dMv=+0.28, par=38.9+-0.6 mas
  conclusion: decent standard?, migrated to G1V post-JM53, color match great
  *add Teffs later*

  conclusion: inappropriate as standard?

# Weak Standards
HD 109358 = bet CVn = HR 4785 = GJ 475

  G1V: MorganAbt73
  B-V(HIP)=0.588+-0.009, whereas B-V(G0V,HIP)=0.585 so its B-V color
  is very representative for its color.
  MorganAbt73 use Bet CVn as a G1V standard, but all other MK refs call it G0V.

  note: classification has migrated from G1V to G2V, but settled post-Keenan89
