We have calculated a grid of solar abundance model
atmospheres.
In addition, we have calculated grids with metallicities , -0.5 and
-0.7 to facilitate comparison to observed LMC and SMC giants. The models
span a range of
and
. The
models are not available for all combinations of these parameters, e.g., at
high
and low
the total radiative acceleration is larger than
the local gravity and hydrostatic models become invalid. In order to minimize
CPU time, the models were calculated for a fixed mass of
. In the
following, we discuss the effects of different model parameters on the resulting
structures and spectra. The effects of the model parameters on the colors
are discussed in the context of evolutionary models by .
