Subleading prong purity for R=0.4 for various grooming algorithms. PYTHIA events are embedded into 0-10% central Pb-Pb data, and PYTHIA jets (truth-level and detector-level) are matched to PYTHIA+PbPb det-level jets. Grooming is then performed, and the subleading prong is identified in the PYTHIA det-level jet as well as the matched PYTHIA+PbPb jet. The PYTHIA+PbPb subleading prong is then matched to the PYTHIA det-level subleading prong if it contains >50% of the PYTHIA det-level prong (by pt). The purity is defined as the fraction of PYTHIA+PbPb subleading prongs that are successfully matched to PYTHIA det-level subleading prongs.
