Unfolded measurement of recoil w, helicity and decay plane angles of semileptonc $\bar{B}^0$ to $D^{*+}$ decays. The data was used to determine $V_{cb}$. Note that the data in the paper does not account for the bin widths. The data shipped with rivet is divided by the bin width and all curves are normalised to the partial width of $\bar{B}^0\to D^{*+} \ell \nu_\ell$
