↵* Slow component has artificial upper limit imposed by spectral analysis, which fitted components having mean transit delay times ranging from 1 s to 190 min.
Data represent upper quartile, median, and lower quartile (75th, 50th, and 25th percentile) values for fractions and mean transit delay times for spectral model impulse response components for 25 experiments. Fractions and mean transit delay times for intermediate components have been combined using Equation 5. Fractions c0, c1, … ,m−1, and cm are dimensionless. Units for mean transit delay times t1, … ,m−1 and tm are minutes.
