Fig. 3.

Heat maps of spatial dispersion in APD₉₀ resulting from intrinsic variability for base cell 1. APD₉₀ maps shown are recorded from base cell 1 with (A) D = 1.171 cm² s⁻¹, (B) D = 0.586 cm² s⁻¹, (C) D = 0.117 cm² s⁻¹, and (D) D = 0.059 cm² s⁻¹. The heat maps shown are generated using the stochastic cell model and are taken from the final beat in the series. APD₉₀ maps are plotted from the central 0.5 cm to reduce distortion due to boundary effects.
