1-exponential	3.87 (2.41)	3.14 (1.27)	2.54 (1.01)	5.91 (5.01)	0.555 (0.257)
2-exponential	3.98 (2.56)	3.16 (1.27)	2.59 (1.09)	5.43 (3.13)	0.557 (0.237)
Hill	2.73 (1.21)	2.47 (1.00)	2.03 (0.83)	3.88 (1.98)	0.488 (0.211)
Kinetic	1.12 (1.31)	1.07 (1.43)	0.95 (1.26)	2.05 (3.69)	0.282 (0.237)

Data are means, with SDs in parentheses. SDs are substantially smaller for Hill model.
