Query: Azimuthal anisotropy of charged jet production in
  $\mathbf{\sqrt{{\textit s}_{\rm NN}}}$ = 2.76 TeV Pb--Pb collisions   Measurements of charged jet production with respect to the second-order
harmonic event plane, quantified as $v_{2}^{\mathrm{ch~jet}}$, in
$\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV Pb--Pb collisions are presented. The
contribution of hydrodynamic flow to the underlying event energy is corrected
for on a jet-by-jet basis. Remaining effects from instrumental resolution and
regional fluctuations in the energy density of the underlying event are
corrected for by unfolding. Significant $v_{2}^{\mathrm{ch~jet}}$ is observed
in semi-central collisions. Qualitative agreement is found with
$v_{2}^{\mathrm{ch+em jet}}$ of jets reconstructed from charged and neutral
fragments and $v_2$ of single charged particles, as well as with predictions
from the JEWEL Monte Carlo model.
