Based on the analysis of the dimuon decay angular distributions in the helicity frame, the polar anisotropy, $\\lambda_\\theta$, is measured as a function of the transverse momentum, $p_\\mathrm{T}$, of the charmonium states, in the 25-120 and 20-100 GeV ranges for the J$/\\psi$ and $\\psi$(2S), respectively.
