A library of theoretical stellar flux spectra. I : Synthetic UBVRI photometry and the metallicity scale for F- to K-type stars

Synthetic colors on the Johnson-Cousins standard UBVRI system of a grid of theoretical model atmosphere flux distributions for late-type stars covering the parameter ranges, 3750 K ≤ T eff ≤ 6000 K, 0.75 ≤ log g ≤ 5.25, 0.50 ≥ [M/H] ≥ −3.00, are presented. These colors are based on new synthetic spectra calculated from the flux-constant, blanketed model atmospheres of Gustafsson et al. (1975) and Eriksson et al. (1979), using the atomic line opacities compiled by Kurucz & Peytremann (1975) and Kurucz (1979)
