Fitted parameter values for ATM with two time constants learned at multiple stimulus levels

	a1	α1	β1	τT1, ms	a2	α2	β2	τT2, ms	Δ, ms	r, ms
Mean ± SD	0.5 ± 0.2	2.4 ± 2.4	12.3 ± 5.8	0.7 ± 0.03	40 ± 4	0.6 ± 1.2	1.6 ± 1.2	40 ± 34	0.01 ± 0.004	2 ± 0.4

First set of parameters corresponds to the faster time constant, second set to the slower time constant. Initial ranges were the same as in Table 2 (n = 5).
