Table 2. Parameters and the quality of the BOLD function prediction.

	Imaginal	Retrieval	Manual
Scale (s)	1.557	1.735	1.201
Exponent (a)	4.760	4.305	4.582
Magnitude: MΓ (a + 1)*	0.733	1.612	4.303
Correlation day 1	0.950	0.946	0.913
Correlation day 5	0.902	0.882	0.953

^*This is a more meaningful measure because the height of the function is determined by the exponent as well as M.
