&OPTIMISE: CHARGES
The position should be given as 3-dimensional coordinates (x,y,z)
and in cm.
As for wires, Garfield does not use scaling factors in its potential
functions for point charges. The potential function used for an isolated
three-dimensional point charge is:
V = q/r
where r is the distance between the charge and the point where the
potential is to be calculated.
It follows that the charge q should be expressed in units of V.cm.
To convert from C to this unit, one should divide by
4\π\ε\<SUB\>0\</SUB\>.
