Identifying the three exponentials from Lanczos

Magnitude	Rate (ms−1)	τ (ms)	Nor. Area	Fitted area	Area error	Fitted τ	τ error
1.5576	5	0.2	0.449187	0.449854	0.001485	0.200481	0.002405
0.8607	3	0.3333333	0.413687	0.412555	0.037820	0.332843	0.001471

Magnitudes and rate constants are from scheme 4-12.17 of Lanczos (7). The time constant (τ) is given by 1/rate. Nor. area is the area of the three exponentials after normalizing to an area of 1.0. The relative error (Eq. 4) for the six estimated parameters was 0.0022 ± 0.0008 (mean ± SD). Estimates are based on 3 × 10⁷ simulated dwell times.
