Description

Abstract Radiation trapping is described by the Holstein equation, a Fredholm integral equation of the second kind. By combining analytical and numerical techniques, the presented code efficiently computes the eigenvalues and eigenfunctions of this equation for three important geometries: plane-parallel slab, long cylinder, and spherically symmetric geometry; all practically occuring spectral lineshapes are considered. The program is written in standard Fortran.
