Chandrasekhar's X- and Y-functions

The bivariational technique is employed to determine Chandrasekhar's (1950) X and Y functions and their first two moments for the case of an isotropic homogeneous finite slab. This information is sufficient for calculating the intensity of radiation emerging from the atmosphere. The present res...

Description
Summary:	The bivariational technique is employed to determine Chandrasekhar's (1950) X and Y functions and their first two moments for the case of an isotropic homogeneous finite slab. This information is sufficient for calculating the intensity of radiation emerging from the atmosphere. The present results show excellant agreement with those of Sobouti (1963). (R.R.)
