Abstract : From many points of view the X and Y functions of Chandrasekhar may be considered to be the basic functions of radiative transfer. In this memorandum the authors present graphs of these functions covering wide ranges of slab thicknesses and albedos for single scattering. The tables on which the graphs are based were obtained by numerically integrating the integrodifferential equations satisfied by the X and Y functions. One of the great advantages of such graphs and tables is that one can test the accuracy of simple approximate expressions. (Author)
