Abstract
The construction of model atmospheres by means of differential corrections is discussed. Either flux or flux gradients may be minimized, with arbitrary weighting with depth. For the simple atmospheres studied, no convergence problems were encountered even when very poor first approximations were used; and flux constancy in the radiative case was generally attained in three or four iterations.
Quantities computed in one iteration may be re-used, not only in subsequent iterations within the model, but also in the construction of other models with differentT eff org; and so the method is particularly suited for grid computations.
