Properties of the native basin, the three well defined denatured basins, and the broad entropic basin; see Figs. 2 and 4

No.	F	〈U〉	TS
1	0	-348.91	0
2	0.72	-351.79	-3.6
3	0.51	-350.28	-1.9
4	0.36	-349.59	-1
Entropic	0.59	-345.02	3.30

F = -kTln(Z) is free energy, 〈U〉 is mean potential energy calculated over all clusters in the basin (determined by the minimum cut and balanced minimum cut procedures), and TS = F - 〈U〉. F and TS are given with respect to the lowest free energy basin. Units are kcal/mol.
