Detector acceptance and signal reconstruction efficiency for ${\mathrm{K}}^{\ast 0}$ and $\mathit{\varphi }$ mesons, which includes reconstruction, track selection and particle identification efficiency. For ${\mathrm{K}}^{\ast 0}$ and $\mathit{\varphi }$ production below $p_{\mathrm{T}}$ $<$ 3 $\mathrm{GeV}/c$, the PID efficiency is relative to the TPC-TOF approach, whereas for $\mathit{\varphi }$ production with $p_{\mathrm{T}}$ $>$ 3 $\mathrm{GeV}/c$ no PID contribution is included, as no particle identification is applied in the analysis
