The program SPHAN estimates the spherical harmonic coefficients of a scalar field by least-square fitting of data values measured on an equal angular grid on a globe.
A procedure that rapidly generates an approximate parametric representation of macromolecular surface shapes is described. The parametrization is expressed as an expansion of real spherical harmonic basis functions. The advantage of using a parametric representation is that a pair of surfaces can be
## Abstract Most electronic structure methods express the wavefunction as an expansion of __N__βelectron basis functions that are chosen to be either Slater determinants or configuration state functions. Although the expansion coefficient of a single determinant may be readily computed from configu
