1  BOHM 1972 is updated with our 1973 ${{\mathit K}^{-}}$, ${{\mathit \pi}^{-}}$, and ${{\mathit \pi}^{0}}$ masses (Reviews of Modern Physics 45 S1 (1973)).
2  These masses have been raised 30 keV to take into account a 46 keV increase in the proton mass and a 21 keV decrease in the ${{\mathit \pi}^{0}}$ mass (note added 1967 edition, Reviews of Modern Physics 39 1 (1967)).
