Category Description 

    Data items in the PDBX_VALIDATE_CLOSE_CONTACT category list the
    atoms within the entry that are in close contact with regard
    the distances expected from either covalent bonding or closest
    approach by van der Waals contacts. Contacts within
    the asymmetric unit are considered.

    For those contacts not involving hydrogen a limit of
    2.2 Angstroms is used. For contacts involving a hydrogen atom 
    a cutoff of 1.6 Angstroms is used.
