The fit includes ${{\mathit D}^{\pm}}$, ${{\mathit D}^{0}}$, ${{\mathit D}_{{{s}}}^{\pm}}$, ${{\mathit D}^{*\pm}}$, ${{\mathit D}^{*0}}$, ${{\mathit D}_{{{s}}}^{*\pm}}$, ${{\mathit D}_{{{1}}}{(2420)}^{0}}$, ${{\mathit D}_{{{2}}}^{*}{(2460)}^{0}}$, and ${{\mathit D}_{{{s1}}}{(2536)}^{\pm}}$ mass and mass difference measurements.

Given the recent addition of much more precise measurements, we have omitted all those masses published up through 1990. See any Review before 2015 for those earlier results.

The largest source of error in the TOMARADZE 2014 value is from the uncertainties in the ${{\mathit K}^{-}}$ and ${{\mathit K}_S^0}$ masses. The systematic error given above is the addition in quadrature of $\pm0.022 \pm0.053$ MeV, where the second error is from those mass uncertainties. 2  The largest source of error in the LEES 2013S value is from the uncertainty of the ${{\mathit K}^{+}}$ mass. The quoted systematic error is in fact $\pm0.043$ + 3 (${\mathit m}_{{{\mathit K}^{+}}}$ $−$ 493.677), in MeV.
