First three non-vanishing components of the SH representation of the two-pion correlation functions, $l=0,m=0$ in (a), $l=2,m=0$ in (b) and $l=2,m=2$ in (c). The centrality and pair momentum ranges for the three functions are given on the plot. The lines show the corresponding SH components of the fit with formula from Eq. (???). |  |
