Supplemental figures: "Measurement of the inclusive J/$\psi$ polarization at forward rapidity in pp collisions at $\sqrt{s} = 8$ TeV"

This short note presents supplemental figures for the paper "Measurement of the inclusive J/$\psi$ polarization at forward rapidity in pp collisions at $\sqrt{s} = 8$ TeV". The 2-D acceptance and efficiency maps are shown in Fig.1, and the simultaneous fits of the angular distributions of J/$\psi$ reconstructed in the di-muon decay channel (number of J/$\psi$ obtained with the initial setting of the invariant mass fit and corrected for acceptance and efficiency effects) are reported in Fig.2 for the Collins-Soper frame and in Fig.3 for the helicity frame. The average $p_{\rm T}$-integrated polarization parameters for the interval $2 < p_{\rm T} < 15$ GeV/$c$ are shown in Fig.4.
