The normalized and centered K-function () increases as the Aggregate-to-Diffuse ratio (ADR) increases.

Each result displayed represents the average of 30 simulated fields of view using the exact same experimental parameters. The x-axis in the right panels shows the radius at which was calculated (rk). Panel A: Left—ADR was varied (the proportion of particles allocated to aggregates) by varying the number of aggregates (Nagg) while keeping the Signal-to-Background ratio (SBR) constant. Note that the signal is added to the background. Since the aggregates have a pre-defined radius, SBR was not the exact same, but varied subtly due to “quantization” effects as the number of aggregates is increased. Right—As ADR increases, increases. This remains true at SNR = 2. Panel B: Left—ADR was varied by varying the SBR while keeping Nagg constant. Right—As ADR increases, increases. This remains true at SNR = 2.
