Single hadron azimuthal asymmetries in the cross sections of positive andnegative hadron production in muon semi-inclusive deep inelastic scattering offlongitudinally polarised deuterons are determined using the 2006 COMPASS dataand also all deuteron COMPASS data. For each hadron charge, the dependence ofthe azimuthal asymmetry on the hadron azimuthal angle $phi$ is obtained bymeans of a five-parameter fitting function that besides a $phi$-independentterm includes four modulations predicted by theory: $sinphi$, $sin 2 phi$,$sin 3phi$ and $cosphi$. The amplitudes of the five terms have been firstextracted for the data integrated over all kinematic variables. In furtherfits, the $phi$-dependence is determined as a function of one of threekinematic variables (Bjorken-$x$, fractional energy of virtual photon taken bythe outgoing hadron and hadron transverse momentum), while disregarding theother two. Except the $phi$-independent term, all the modulation amplitudesare very small, and no clear kinematic dependence could be observed withinexperimental uncertainties.
