Typical spectral components for our AO semianalytical computations. Top: input spectra for turbulence and noise, and the measurement power transfer function |hi(f; αiGi)|2 for three αiGi values. Bottom: corresponding measurement power spectra 
. For this example, τ = 2T, and fS = 500 Hz, yielding gcrit ≈ 0.61 and fcrit = 50 Hz.
