A simple and reliable method has been established for the definition of the depth of formation of lines in a stellar atmosphere. It is based on the determination of the level of emission of the reemitted line radiation. The new definition, which is applied in this paper to the solar case, does not s
A new definition of the effective depth of line formation is given which incorporates its dependence on the angle of emergence as well as on the position within the line. Solution obtained for isotropic scattering in the third approximation of discrete ordinates explains: (i) Variation of equivalent
