Invariant-mass distributions $M(\mathrm{K}\pi\pi {\rm K^0_S}) - M(\mathrm{K}\pi\pi)$ of ${\rm D_{s1}^+}$ (top panels) and ${\rm D_{s2}^{*+}}$ (bottom panels) candidates and charge conjugates in the $2< \pt< 24$ GeV/$c$ interval, for the INEL$>$0 and HMV0 (0-0.1% V0M) samples. The blue solid lines show the total fit functions described in the text, and the red dashed lines represent the combinatorial background. The raw-yield ($S$) values are reported together with their statistical uncertainties, as well as the estimated significance of the signal (Signif.).
