Scintillation bandwidth evolution with frequency for a two-screen system. Black dots represent mean values from 30 simulations with error bars indicating the standard error. The RP = 1 and RP = 3 lines separate the regions where screens are in the unsolved, partially resolved, and highly resolved regimes. Fits to the simulation values show a broken power-law distribution (ν_s,MW ∝ ν^α): α ≈ 2 in the resolved region and α ≈ 4 in the unresolved region.
