  Scattering at physical pion mass is still an exploratory field in lattice
QCD. This generally involves the extraction of excited states through
multi-particle correlators on systems with resonances. In that context,
distillation has been demonstrated to be effective both as a smearing kernel
and a computational tool. Motivated by the study of the smearing profile of the
distillation operator, we compare stochastic and exact distillation cases for
different numbers of Laplacian eigenvectors using an RBC-UKQCD $N_f=2+1$
domain-wall fermion lattice with a physical pion mass.
