ed for the numerical integration is an
Euler-MacLaurin scheme for the radial components (with a modified
Mura-Knowles transformation)
and a Lebedev
scheme for the angular components.  Within this numerical
integration procedure various levels of accuracy have been defined and
are available to the user.  The user can specify the level of accuracy
with the keywords; xcoarse, coarse, medium, fine, and xfine.  The
default is medium.
