1  The 2014 CODATA mass difference in $\mathit u$ is ${\mathit m}_{{{\mathit n}}}–{\mathit m}_{{{\mathit p}}}$ = 1.001$~388~449~00(51){\times }10^{-3}\mathit u$.
2  The 2010 CODATA mass difference in $\mathit u$ is ${\mathit m}_{{{\mathit n}}}–{\mathit m}_{{{\mathit p}}}$ = 1.388$~449~19(45){\times }10^{-3}\mathit u$.
3  Calculated by us from the MOHR 2008 ratio ${\mathit m}_{{{\mathit n}}}/{\mathit m}_{{{\mathit p}}}$ = 1.00137841918(46). In u, ${\mathit m}_{{{\mathit n}}}–{\mathit m}_{{{\mathit p}}}$ = 1.38844920(46)${\times }10^{-3}~$u.
4  Calculated by us from the MOHR 2005 ratio ${\mathit m}_{{{\mathit n}}}/{\mathit m}_{{{\mathit p}}}$ = $1.00137841870$ $\pm0.00000000058$. In u, ${\mathit m}_{{{\mathit n}}}–{\mathit m}_{{{\mathit p}}}$ = $0.0013884487$ $\pm0.0000000006~$u.
5  Calculated by us from the MOHR 1999 ratio ${\mathit m}_{{{\mathit n}}}/{\mathit m}_{{{\mathit p}}}$ = $1.00137841887$ $\pm0.00000000058$. In u, ${\mathit m}_{{{\mathit n}}}–{\mathit m}_{{{\mathit p}}}$ = ($1.3884489$ $\pm0.0000006){\times }10^{-3}~$u.
6  Calculated by us from the COHEN 1987 ratio ${\mathit m}_{{{\mathit n}}}/{\mathit m}_{{{\mathit p}}}$ = $1.001378404$ $\pm0.000000009$. In u, ${\mathit m}_{{{\mathit n}}}–{\mathit m}_{{{\mathit p}}}$ = $0.001388434$ $\pm0.000000009~$u.
