Figure 5.

Distribution of ${\hat{k}}_{\text{on}}$ and ${\hat{k}}_{\text{off}}$ for both recovery-curve-based estimation (yellow) and pixel-based estimation (red) for D = 5 × 10⁻¹⁰ m²/s, k_on = 0.5 s⁻¹, k_off = 0.5 s⁻¹, and a = 0.01. The true parameters are indicated (black plus sign) as well as the line k_on = k_off (black). To see this figure in color, go online.
