Delley partitioning about integratorxx HOT 1 OPEN

The Baker et al 1994 paper defines the following weighting

in this scheme the angular quadrature weights are derived from superpositions of spherical atomic densities for all the atoms that make up the system being studied

$$ w_A({\bf r}) = \rho_A^n({\bf r}) / \sum_{B} \rho_B^n({\bf r}) $$

where $n$ is a parameter; $n=2$ was used in that paper.
