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.
