Projections of the 3D Cartesian representations of the correlation functions for events with $23\leq N_{ch}\leq29$ and pairs with $0.3< k_{\rm T}< 0.4 $GeV/$c$. To project onto one $q$-component, the others are integrated over the range $0-0.16 $GeV/$c$. Dashed lines show analogous projections of the Gaussian fit |
