Query: Measurement of masses of $\Xi_c(2645)$ and $\Xi_c(2815)$ baryons   We report a precise measurement of masses of the $\Xi_c(2645)$ and
$\Xi_c(2815)$ baryons using data collected by the Belle experiment at the KEKB
$e^+ e^-$ collider. The states $\Xi_c(2645)^{0,+}$ are observed in the
$\Xi_c^{+,0}\pi^{-,+}$ decay modes, while the $\Xi_c(2815)^{0,+}$ are
reconstructed in the $\Xi_c(2645)^{+,0}\pi^{-,+}$ decay modes.
