The cross sections are shown as functions of a) the muon pseudorapidity $\eta ^\mu $, b) the muon transverse momentum $p\ensuremath  {_\@mathrm {T}} ^\mu $, c) the jet transverse momentum $p\ensuremath  {_\@mathrm {T}} \ensuremath  {^\@mathrm {jet 1}}$ of the highest transverse momentum jet, d) the photon's momentum fraction $\ensuremath  {x \ensuremath  {_\@mathrm {\gamma }}\ensuremath  {^\@mathrm {obs}}}$ entering the hard interaction, and e) the azimuthal angle difference $\ensuremath  {\delta \phi \ensuremath  {_\@mathrm {jets}}}$ between the jets. The inner error bars show the statistical error, the outer error bars represent the statistical and systematic uncertainties added in quadrature. The NLO QCD predictions are corrected to the hadron level (solid line) using the PYTHIA generator. The shaded band around the hadron level prediction indicates the systematic uncertainties as estimated from scale variations (see text). Predictions from the Monte Carlo generator PYTHIA (dotted line) are also shown.}}{12}}
