2D lattice with position variance

A position variance parameter describes fluctuations of particle position around lattice points. It gives rise to an attenuation factor of Debye-Waller type.

It can be set using the method setPositionVariance(variance) of class Interference2DLattice. The argument variance is in nm$^2$.

By default the variance is zero.

Example: square lattice without and with variance

A square lattice of hemispheres on a substrate, for different lattice orientation angles xi.
