Columns:
R1     - residue 1
R2     - residue 2
P#     - NOESY peak index (number)
UPL    - upper limit constraint (in Angstroms)
Conf   - confidence score based on chemical shift matching to the NOESY cross peak
A1     - atom 1 (H is the backbone amide proton HN)
A2     - atom 2 
 
How to interpret the data:
peak 17 is assigned to residues 79HN and 77HN
peak 20 has 4 possible assignments, at least one of which is consistent with the structure
peak 23 has 9 possible assignments, at least one of which is consistent with the structure
