NOE distance restraints were split in two sets. One set involved residues that were identified as beeing affected by conformational exchange by relaxation dispersion experiments. These distances were assigned an additional 1A to the upper distance limit. Reported close contacts are due to conformational heterogeneities in the set of NOES. The dynamical properties of this protein have been described in depth in the J. Biomol. NMR reference cited above.
