There is a clear dependence on the available experimental data for the evidence of particular models. Furthermore, the final example shows the chemical information about a particular system may not be completely reflected in the experimental data. In this final case, the chemically distinct nature of the phospholipid heads and tails is lost. While this current work has focused on the application of this Bayesian framework to the problem of Langmuir-Blodgett monolayers, the methods used a completely generalisable to any reflectometry modelling. Therefore, we hope that greater consideration will be given to the information content of neutron and X-ray reflectometry measurements in the future.
