The following Run-2 plots are produced with simple selections, explained in the figure caption.

Invariant mass distributions for oppositely charged muon candidate pairs that pass various triggers.
Events are reconstructed from pairs of muons passing "Tight" offline quality criteria, which are fit to a common vertex, using the inner detector track parameters, with a $\chi^{2} < 20$ for the one degree of freedom. Muons are also required to have an absolute pseudo rapidity less than 2.3, and have transverse momentum at least that of the trigger threshold (for the single-muon trigger the thresholds of 20 and 4 GeV are used). The dimuon triggers require two muons at L1, passing thresholds of $p_{\rm T} > 4$ or 6 GeV, which are confirmed at the HLT. Pairs of oppositely charged muons are fit to a common vertex, using the inner detector track parameters, and invariant mass requirements made to restrict events to the charmonium, b-hadron and bottomonium invariant mass ranges. For comparison, the lowest threshold unprescaled single muon trigger is shown. This single-muon trigger is required to pass the 15 GeV threshold at L1, and 20 GeV at the HLT. The yields of events collected for each trigger are overlaid, where overlapping events collected by multiple triggers are retained in each histogram; hence the integral of events from all histograms is greater than the total event yield. For certain periods of running, trigger prescales were applied, reducing the effective yield of events collected by those triggers. The supporting dimuon trigger, which covers the full mass range of interest was also prescaled throughout the period of running.
