The reconstruction of particle-level top quarks and anti-quarks is implemented in this module. Measurements at $\sqrt{s} = 8 \text{TeV}$ are based on parton-level information in the full phase space using MADGRAPH+PYTHIA6. To match the particle-level top quark distributions to the measurements unfolded to the parton-level, a correction function to the particle-level distributions, derived using the same MADGRAPH+PYTHIA6 configuration that was used for the original measurement of the data points, is applied. Using the same MC configuration as used for the unfolding to correct back the parton-level to particle-level, the model dependence introduced in unfolding to parton-level and extrapolating the measurement to the full phase space is eliminated. See the paper for full object selection and correction details.
