 charge density fitting basis set can also be specified in the 
input directives for the DFT module.  This basis set is used for the 
evaluation of the Coulomb potential in the Dunlap scheme<A NAME="tex2html28"
  HREF="footnode.html#foot3421"><SUP>11.1</SUP></A>.
The charge density fitting basis set must have the name <TT>"cd basis"</TT>.
This can be the actual name of a basis set, or a basis set can be 
assigned this name using the <code>SET</code> directive, as described in
Section <A HREF="node7.html#sec
