Parameters of the impulse responses.

Experimentally-determined impulse responses of three respirometry chambers in five different flow rates were modeled in four ways. In the first three models, αtme−βt has been fitted to the data. Here m, α, and β are constant parameters that are needed to fit this curve (αtme−βt) to the experimental data (see text for details). In the first one, m is considered as a real number. In the second, one we restricted the m to be an integer and then found the parameters. In the third one, we decreased m to the lowest integer number without having more than 10% ITAE (∫0∞|e|dt). In the last one, we forced m to be zero in order to recover the ZT model.
