Query: CP violation and mixing in the charm sector at Belle, and current HFAG
  averages   Current HFAG averages of the mixing and CP violation parameters in the $D^0$
meson system is to be reviewed. We present recent Belle measurements of the
mixing parameters $x$ and $y$ using $D^0\rightarrow K^0_S\pi^+\pi^-$, and
$y_{CP}$ and $A_\Gamma$ from $D^0\rightarrow h^+h^-$, $D^0\rightarrow
K^-\pi^+$, where $h$ denotes $K$ or $\pi$. Belle measurements of direct CP
violation in $D^+\rightarrow K^0_S\pi^+$, $D^0\rightarrow h^+h^-$, and
$D^+\rightarrow K^0_SK^+$ decays together with $\Delta A^{hh}_{CP}$ are to be
presented.
