In the mesh representation, the density is given only at the mesh points. In order to calculate the skin thickness in the, say, x-axis more accurately than the mesh spacing, we take the following procedures:
  1. We interpolate the density at the points of intersections between the x-axis and the mesh planes x=(i+1/2)a using polynomials of order two in y2 and z2.
  2. We interpolate to arbitrary points in the x-axis for the logarithm of the density using polynomials of order three in x.
The resulting density in logarithmic plots versus x shows no artificial ripples due to the interpolations.
