The algorithm by
Lee and Richards (1971) is
used to compute the accessible surface area (MODE=ACCEss)
or the contact area (MODE=CONTact).
The routine uses the van
der Waals radii (Eq. 4.10) for all atoms as
specified in the parameter statement.
Upon completion, the accessible surface area for each
selected atom is stored in the RMSD atom property
(in Å
units).
