Hi Edo,

That works fine, thanks. Performance wise there is little difference between this and putting in the localised basis sets as I described above... but I can be much more confident about the influence an approach like you have described is having in a physical sense.

Thanks for all your help.

For anyone else who reads this, there are limits on the range for the "tiny charge".

For charge >= 1e-8, an error occurs due for a non-integral number of electrons
For charge <= 1e-21, the ghost atom error persists.
