15 Biso instead of Uiso
      6 Uij multiplied by 1E4?
      5 Digits missing from some Uij values?
      4 Bij instead of Uij
      3 Bij instead of Uij for just one atom? (???) Or refinement problems?
      2 Two Uij values stand out. Manual data entry error? Or refinement problems?
      2 Bij instead of Uij?
      1 Values for one atom ('C(1)') very large. Problems with refinement?
      1 Two Uij values stand out. Manual data entry error? Uij multiplied by 1E4?
      1 Two Uij values stand out. Manual data entry error? (Typed "9" instead of "0"?)
      1 Two Uij values stand out. Manual data entry error?
      1 Three Uij values stand out. Manual data entry error? Uij multiplied by 1E4?
      1 The first (U11) value on *some*, but not *all*, hydrogens seems to be converted to B instead of U (???)
      1 Some atoms seem to have Uij, some probably have Biso specified as U11. Manual data entry error?
      1 Reason for large Uij not clear at all. Similar to 1544873
      1 Reason for large Uij not clear at all.
      1 Possible reason
      1 One Uij value stands out. Problems with refinement?
      1 One Uij value stands out. Manual data entry error? Or refinement problems?
      1 One Uij value stands out. Manual data entry error? Digits missing from some Uij values?
      1 One Uij value stands out. Manual data entry error?
      1 Large negative U23 for some atoms. Problems with refinement?
      1 Heavy atoms seem to have Uij, hydrogens probably have Biso specified as U11. Manual data entry error?
      1 Extra digits for some Uij values? Manual data entry error?
      1 Digits missing from some Uij values? Problems with refinement?
      1 Digits missing from some Uij values? Manual data entry error?
      1 Biso instead of Uiso; problems with orthogonalisation?
      1 Biso instead of Uiso; bad orthogonalisation?
