Rate of the isolated single-muon trigger, mu24i, at the event-filter a as a function of pseudorapidity ${\mathit{\eta }}_{\mathrm{EF}}$ for all combined-muons (light histogram) and for the ones associated with offline reconstructed muons (dark histogram), b as a function of the transverse momentum $p_{\mathrm{T}}$ threshold at the event-filter (EF) at an instantaneous luminosity of $7\times {10}^{33}$ cm${}^{-2}$ s${}^{-1}$, for combined-muons in the data (dots) compared to the expectations from $W$- and $Z$-bosons production and from the data-driven estimate for multi-jet production, as described in the legend
