What it does: interpolate each vector on the proportional part.
It takes a row number, the proportional part and interpolates
linear . The contour is provided, and the 3d ortho @ the
interpolated proportional part. Modular, i.e: not programmed.
The data set appeared years ago in the Mthcad collab,
a bit hairy but a superb demo. Admited, a Fourier convolution
should be applied, but it seems there is no datum plane, or
most likely the datum plane is 0.
As it looks, purely noise or some physical phenomenon
...particles random in each direction XYZ.
Absence of an abstract about this data set.
