Fig. 4: κ-dependence of MLI output in class (c).
From: Signatures of correlation of spacetime fluctuations in laser interferometers

Scaled output signal PSDs SNC(ν) = κ SC(ν) vs ν are plotted for exponential ρES corresponding to κ = 0.025 (red solid), κ = 0.01 (green dashed), κ = 0.005 (brown dot-dot-dashed), and κ = 0.0025 (pink dotted), demonstrating the 1/ν2 behaviour at the high-frequency limit.
