Invariant-mass distributions after combinatorial background subtraction for ${\rm K^{*0}}$ and $\phi$ candidates in the multiplicity class 0$-$10% and transverse momentum range 2.2 $\leq$ $p_{\mathrm{T}}$ $<$ 3.0 GeV/$c$ in the rapidity interval -0.3 $< y <$ 0 (panels (a) and (b)) and 0 $< y <$ 0.3 (panels (c) and (d)). The ${\rm K^{*0}}$ peak is described by a Breit-Wigner function whereas the $\phi$ peak is fitted with a Voigtian function. The residual background is described by a polynomial function of order 2.
