Projections of the 3D Cartesian representations of the correlation functions onto the $q_{out}$, $q_{side}$ and $q_{long}$ axes for pairs with $0.2 < k_{\rm T} < 0.3 $GeV/$c$, for three multiplicity ranges. To project onto one $q$-component, the others are integrated over the range $0-0.16 $GeV/$c$ | ![](https://alice-publications.web.cern.ch/sites/default/files/papers/3872/alifemto2.fig1b-26754.png ) |
