Moments of the SH decomposition of the correlation functions for events with $23\leq N_{ch} \leq29$ and pairs with $0.3< k_{\rm T}< 0.4 $GeV/$c$. The dashed line shows the Gaussian fit, the dash-dotted line shows the background component, the dotted line show the femtoscopic component. | ![](https://alice-publications.web.cern.ch/sites/default/files/papers/3872/alifemto2.fig7a-26778.png ) |
