.SH "Detailed Description"
.PP 
An implementation of a Lebedev angular integrator\&. 

It uses code written by Dr\&. Dmitri N\&. Laikov\&.
.PP
This can generate grids with the following numbers of points: 6, 14, 26, 38, 50, 74, 86, 110, 146, 170, 194, 230, 266, 302, 350, 386, 434, 482, 530, 590, 650, 698, 770, 830, 890, 974, 1046, 1118, 1202, 1274, 1358, 1454, 1538, 1622, 1730, 1814, 1910, 2030, 2126, 2222, 2354, 2450, 2558, 2702, 2810, 2930, 3074, 3182, 3314, 3470, 3590, 3722, 3890, 4010, 4154, 4334, 4466, 4610, 4802, 4934, 5090, 5294, 5438, 5606, and 5810\&.

.PP
Save the base classes (with save_data_state) and the members in the same order that the \fBStateIn\fP CTOR initializes them\&. This must be implemented by the derived class if the class has data\&. 
.PP
Reimplemented from \fBsc::AngularIntegrator\fP\&.
