Acceptance and efficiency corrected angular distributions of the decaying pion in the rest frame of the D$^*$ candidates with $4 < p_{\rm T} < 6$ GeV/$c$ and with $15 < p_{\rm T} < 30$ GeV/$c$ in the rapidity interval $0.3 < |y| < 0.8$ for Pb$-$Pb collisions in the 30$-$50% centrality class. The distributions are fitted with the function from Eq.1. Only statistical uncertainties are shown.
