ALICE measurements of $\theta_{\rm g}$ distributions in pp collisions at $\sqrt{s}=5.02$ TeV withsoft drop, compared with NLL$^\prime$ predictions carried out with SCET and corrected for non-perturbative effects using either PYTHIA8 or Herwig7. The distributions are normalized such that the integral of the perturbative region defined by $\theta_{\rm g} > \theta_{\rm g}^{\rm NP}$ (to the right of the dashed vertical blue line) is unity The non-perturbative scale in Eq. 7 is taken to be $\Lambda$=1 GeV/$c$ In determining the normalization, intervals that overlap with the dashed blue line are considered to be in the non-perturbative (left) region.
