simulated annealing	The 1H-1H NOE amplitudes should be treated only according to the flexibility of the corresponding backbone or side chain groups: derived from the heteronuclear NOE, R1, R2, 1chch(dipolar cross-correlation contribution to R1), 2chch(dipolar cross-correlation contribution to R2), and 3J scalar coupling constant values.
