The \mT dependence of the effective radius \reff (left) and the core radius \rcore (right) for different multiplicity classes. The black data points are from a previous analysis using a high-multiplicity data set collected by ALICE at \onethree~. Here, INEL$>0$ refers to inelastic pp collisions with at least one charged particle in the event within $|\eta| 1.0$~, while 0–0.17\% denotes the highest-multiplicity class, corresponding to the top 0.17\% of events in the charged-particle multiplicity distribution. The bands correspond to the parametrization of the \mT dependence for the different multiplicity classes.
