abstract
Recent data for the masses of $D$ and $D^*$ mesons determined using methods of lattice QCD for several values of the charm quark mass different from its physical mass are analysed in Heavy Quark Effective Theory. Nonperturbative parameters are extracted that arise at order ${\cal O}(1/m_c)$ in the heavy-quark mass expansion of a heavy-light meson mass. The determined parameters are used to establish the charm quark masses corresponding to the employed lattice sets.

The first data-driven determination of the HQET parameters mu_pi^2, mu_G^2, rho_D^3 and rho_LS^3 for D0, D+ and Ds mesons is obtained from inclusive semileptonic decay widths and electron energy moments.
