The DFT module uses Lebedev-Laikov grids, using the code distributed through CCL (http://www.ccl.net/).

.. code-block:: text
|

|
|

|
This subroutine is part of a set of subroutines that generate
|
||
|
Lebedev grids [1-6] for integration on a sphere. The original
|
||
|
C-code [1] was kindly provided by Dr. Dmitri N. Laikov and
|
||
|
translated into fortran by Dr. Christoph van Wuellen.
|
||
|
This subroutine was translated using a C to fortran77 conversion
|
||
|
tool written by Dr. Christoph van Wuellen.
|
||
|
|
||
|
Users of this code are asked to include reference [1] in their
|
||
|
publications, and in the user- and programmers-manuals
|
||
|
describing their codes.
|
||
|
|
||
|
This code was distributed through CCL (http://www.ccl.net/).
