(a) Simulation of scanning XRR curves after the deposition at t = t1 and t = t2, using the resolution elements [\sigma_{q_z}] = 0 Å−1 (dotted lines) and [\sigma_{q_z}] = 0.002 Å−1 (continuous lines). The upper curve is shifted for a better comparison. At t2 = [t_1+\Delta t], the influence due to [\sigma_{q_z}] increases. (b), (c) Simulation of stationary XRR curves at [\alpha_{\rm{fix}}] = 1.6° for a deposition time t = 600 s with (b) [\sigma_{q_z}] = 0 Å−1 and a linear increase in roughness [[\sigma(t)] = t × 0.005 Å/s], and (c) including only a finite resolution ([\sigma_{q_z}] = 0.002 Å−1, σ = 0 Å). The envelopes of all curves are shown as red lines. The envelope of the simulated curve with [\sigma_{q_z}] = 0 Å−1 and σ = 0 Å is presented by grey lines in (b) and (c) for comparison.
