The \mT dependence of the effective radius \reff (left) and the core radius \rcore (right) for two different multiplicity classes. The red data points correspond to the extraction of the radii using this analysis's full MB data set. The black data points are from a previous analysis using a high-multiplicity data set collected by ALICE at \onethree . The bands correspond to the parametrization of the \mT dependence for the different multiplicity classes.
