  The ATLAS experiment measures the production of muons coming from the decays
of heavy flavour particles in the kinematic interval 4<p_T<14 GeV and |eta|<1.
The measurement is performed in sqrt(s) = 2.76 TeV pp collisions and over the
centrality range of 0-60% in sqrt(s_NN) = 2.76 TeV Pb+Pb collisions. The heavy
flavour muon differential cross-sections and per-event yields are measured in
pp and Pb+Pb collisions, respectively. The nuclear modification factor measured
in 0-10% most central collisions is observed to be approximately equal to 0.4
and independent of p_T within uncertainties, which indicates suppressed
production of heavy flavour muons in Pb+Pb collisions. The muon yields are also
measured as a function of the azimuthal angle with respect to the event plane.
Fourier coefficients associated with the second harmonic modulation vary slowly
with p_T and show a systematic variation with centrality that is characteristic
of other elliptic anisotropy measurements.
