The plotfile contains an interpolated version of the potentials, which can be used for plotting the potentials.

For tabulated potentials there is also the plotpointfile which contains only the data at the sampling points.

The format is very simple, the potentials are written in the same order as in the potential file and are separated by two empty lines.
