Normalized scattering and absorption coefficients as a function of optical depth τ for Phoenix stellar model atmospheres. Different panels show the opacities for various parameters of the models that are described in a legend of each panels. Panels a) and b) present the opacities for stars with effective temperature of 5800 K and log g of 4.5 for different wavelengths of 4000 Å and 7000 Å, respectively. Panels c) and d) are for stars with the same log g and at the same wavelengths, respectively but for effective temperature of 5300 K. Panels e) and f) are for stars with identical effective temperature of 4500 K and at the same wavelength of 4000 Å except for two different values log g of 4.5 and 3.0, respectively.
