Particle density does not seem to be taken into account when calculating R/T parameters.
Simple example is a 2D lattice of relatively dense particles (e.g. lattice parameter 2*radius) in an air layer. Specular reflectivity if this situation is calculated equal to the pure substrate, although the layer SLD is 30%-40% of the particle SLD. It's not possible to circumvent this by just setting the layer sld to the actual density, as this decreases the contrast for the in-plane structure factor.

Expected behavior: The particle density is calculated and the SLD for the R/T calculation is the particle SLD * particle density + layer SLD * (1-particle density)
