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. Measurements of the ${{\mathit D}_{{{s}}}^{\pm}}$ mass with an error greater than 10 MeV are omitted from the fit and average. A number of early measurements have been omitted altogether.
