Angular distributions in between the muons $B_c^+\to J/\psi\pi^+$ and $B_c^+\to J/\psi\pi^+\pi^+\pi^-$ with the muons from $J/\psi\to\mu^+\mu^-$ and mass distributions in $B_c^+\to J/\psi\pi^+\pi^+\pi^-$. The data were read from the plots in the paper and may not be corrected for efficiency and acceptance.
