Figure 2
The experimental R(q,t) in (a) is compared with different fitted XRR curves. (b) shows the CNN prediction with a χ2 deviation value of 5.0; a manual Parratt32 fit (c) has a lower deviation of [\chi _{\rm Parratt}^2] = 1.7 as it also fits experimental noise (red circle). The growth model co-refinement (d) yields [\chi _{{\rm co}{\hbox{-}}{\rm refine}}^2] = 9.2.
