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.本次展示的每一项结果，均为在完全一致的实验参数下，对30个模拟视场取平均后得到的均值。右侧面板的横轴为计算相关指标时所采用的半径（rk）。图A 左侧：通过调整聚集体数量（Nagg）来改变聚集分配比例（ADR，即分配至聚集体的粒子占比），同时保持信号背景比（SBR，Signal-to-Background Ratio）恒定。需注意，信号会叠加至背景之上。由于聚集体具有预设半径，随着聚集体数量增加，受“量化”效应影响，实际信号背景比会存在细微偏差，无法完全保持恒定。图A 右侧：随着聚集分配比例（ADR）升高，对应指标上升。该结论在信噪比（SNR，Signal-to-Noise Ratio）=2时依然成立。图B 左侧：通过调整信号背景比（SBR）来改变聚集分配比例（ADR），同时保持聚集体数量（Nagg）恒定。图B 右侧：随着聚集分配比例（ADR）升高，对应指标上升。该结论在信噪比（SNR）=2时依然成立。
