Abstract:
Synthetic spectra have been computed for F and G dwarf stars, using a
number of values of chemical abundances, Doppler broadening velocity
and damping constants. Filter transmission function have been
convolved with thee spectra to yield color indices in 3 photometric
systems.

Note (1): the continuum colors are c-Δc, e.g. (U-B)-Δ(U-B)
or (B-V)-Δ(B-V)
Note (2): the proportion of the elements are, on the logarithmic scale H=12:
He=10.80; C=8.62; N=7.88; O=8.86; Mg=7.10; Sc=3.20; Ti=4.58;
V=3.97; Ca=6.19; Cr=5.18; Mn=4.95; Fe=6.62; Co=4.77; Ni=5.09; Ce=1.95
