Noise considerations for lifetime unmixing. Lifetime recovery was simulated assuming Poisson statistics, i.e., ${\sigma }_y^2=\beta y+{\sigma }_r^2$,¹³ with β=6.53 and a dynamic range of 2¹⁴ (4×4 hardware and 2×2 software binning). (a) Relative amplitude uncertainty for equal amplitude probes of lifetimes τ₁ and τ₂. (b) Relative amplitude uncertainty of the first amplitude component for varying amplitudes a₁ and a₂ over the dynamic range of the instrument, with fixed lifetimes τ₁=1 ns and τ₂=1.2 ns. The white lines in (a) and (b) indicate the 30% relative uncertainty contours.
