A modified Rybicki method with partial redistribution.
Abstract
A new approximate numerical method is presented that retains the basic computational advantages of the Rybicki method while still being capable of handling partial redistribution transfer problems. The crucial point of this method is to consider the frequency which separates the complete redistribution core region from the coherent wing region, to be depth-dependent. The present method yields excellent agreement with exact calculations and gives much better results than any depth-independent version of the partial coherent scattering approximation.
