G1III There appears to be no good southernly accessible G1III standards. OU And might be worth trying as G1III standard (J2349+3625; V=5.9). Keenan89 standard: HD 204613 - G1IIIa CH1.5 (J-H)(G1III) = 0.349 ; smoothed relation from giants in Skiff compendium w/i 15 deg of NGP, 2MASS photometry AAA flags => adopt (J-H)(G1III) = 0.349 [updated 10/30/2020] (H-Ks)(G1III) = 0.086 ; smoothed relation from giants in Skiff compendium w/i 15 deg of NGP, 2MASS photometry AAA flags => adopt (H-Ks)(G1III) = 0.086 [updated 10/30/2020] # No standard MK43, JM53, Houk, GrayCorbally10 and GrayNstars do not list a G1III standard. Gray classifies only one star as "G1III CaIIe" (HR 9024 = HD 223460) # Candidate standard OU And = HR 9024 = HD 223460 (J2349+3625; V=5.9) *G1III CaIIe: Gray01 G1IIIe: Cowley79(CaII em) G2III: Harlan74 G5: Cannon Chromospherically active, single G-type giant (Gondoin03, Bradshaw07) in the Hertzsprung gap with high X-ray luminosity and showing X-ray emission from coronal plasma up to ~10^8 K! ASCC parallax = 7.71+-0.34 mas. B-V = 0.806 (HIP) [possibly reddened given its distance and red colors compared to other early Gs], I estimate Mv = 0.3, so clearly evolved. GCVS calls it a FK Com-type, with variability of ~5.87-5.94 mags at V band. deMedeiros00 lists vsini = 21.5 km/s, so not a very fast rotator. Adopt "G1III CaIIe" from Gray01. eps Leo = HD 84441 (J0945+2346; V=3.0) G1IIIa: Keenan89(non-standard) But not called "G1IIIa" by others. # Variant HD 204613 (J2127+5719; V=8.2) *G1IIIa: CH1.5: Keenan89 G0III:p Sr: Bond70(Sr,CH very strong) G2: Alksnis58
