N2 - We describe a method to measure and correct for the incoherent component of energy flow arising from multiple interactions from jet shape and substructure observables of massive jets. The correction is a function of the jet-shape variable of interest and not a universal property. Such a correction is expected to reduce biases in the corresponding distributions generated by the presence of multiple interactions and to improve measurement resolution. This data-driven technique is not subject to uncertainties coming from the use of theoretical calculations. Corrections are derived for jet mass, angularity, and planar flow, and are found to be in good agreement with data on massive jets observed by the CDF collaboration. Finally, we comment on the linkage with the concept of jet area and jet mass area.
