Normalised (mean) density at the densest pixel and at the 99^th percentile (indicated by darker and lighter colours; respectively) for different spatial resolutions. The mSI runs at different resolutions are indicated with the dotted line for run mSI₁₀₂₄, mSI₅₁₂, and mSI using green, orange, and blue, respectively. The PSI runs PSI10₁₀₂₄, PSI10₅₁₂, and PSI10 have the same colour coding as the mSI runs.
