Two-particle per-trigger yield measured for charged track pairs with $1< p_{\rm T,trig} <2$ GeV/$c$ and $1< p_{\rm T,assoc} <2$ GeV/$c$ within the multiplicity range $32 < N_\mathrm{ch} \leq 37$. The jet fragmentation peak has been truncated to ensure a better visibility of the long-range structure. The right panel shows the zero-suppressed projection to $\Delta\varphi$ overlaid with $F(\Delta\varphi)$ (red line) and the area in which the ridge yield is extracted (shaded area). The blue and purple lines represent the second and third harmonic terms of $F(\Delta\varphi)$.
