 Jet mass scale characterized by the relative mean and most probable value of the response. Jet mass scale is shown as a function of probe jet \pt{} for background fluctuations and the full response including detector effects, using anti-\kt{} PYTHIA jets with $R=0.4$ embedded into central \PbPb{} collisions.
