chvd This subroutine is part of a set of subroutines that generate
|
|
chvd Lebedev grids [1-6] for integration on a sphere. The original
|
|
chvd C-code [1] was kindly provided by Dr. Dmitri N. Laikov and
|
|
chvd translated into fortran by Dr. Christoph van Wuellen.
|
|
chvd This subroutine was translated from C to fortran77 by hand.

|
chvd publications, and in the user- and programmers-manuals
|

cvw Given a point on a sphere (specified by a and b), generate all
|

cvw the equivalent points under Oh symmetry, making grid points with

cvw The variable num is increased by the number of different points
|
