It seems that 5-Gaussian is indeed the accepted technical term
for the 9-parameter expansion:
Given that a5=c and b5=0, the 5th Gaussian can be a constant.
Continuing this reasoning, even a binary mumber can be represented
as series of Gaussians.....a=0,b=0; a=1, b=0
This is called 'Gomputing'.

I wrote that - is a constant a Gaussian? Anyway that is how I got 5 - and it
is the
9-parameter Cromer-Mann approximation..
And Yes - each component is added to the B value to build up the real space
atomic density.
as you show.
