| 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  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  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.

| The following Run-1 plots are produced with simple selections, explained in the figure caption. |

| Di-muon invariant mass distributions for events collected in a single run by two trigger menus: muon stream and B-physics stream.Whilst the individual triggers dedicated to J/ψ→μμ, Υ→μμ and Bs→μμ in each menu are the same, the prescales in the B-physics stream are lower, leading to a higher yield of di-muons.This data sample was not reconstructed immediately but stored in raw form on disk until the long shutdown began. In this way the muon trigger output bandwidth was maximally used without overloading the reconstruction running during data taking.This “delayed stream” approach was used for the majority of 2012. |

| As above but for a specific trigger which requires two muons, both in the barrel region of the detector, both with pT greater than 4 GeV, and in the invariant mass range 2.5 < Mμμ < 4.2 GeV.The very large difference in yield is purely a function of the different prescales in the two menus. |

| Invariant mass of oppositely charged muon candidate pairs selected by a variety of triggers. The trigger naming convention is explained as follows
EF_2mu4_DiMu trigger was prescaled for some of the later data taking, which is why it collects fewer events. The integral of the histograms will be greater than the total number of candidates collected, since the different trigger samples overlap. |

Events which fire a variety of di-muon triggers, with one or two muons at level 1 confirmed at the high level trigger (HLT), are included. The pair of muons are required to have a minimum pT of (2.5, 4) GeV as calculated by the offline reconstruction. At least one high-quality (“combined”) muon is required in each pair. The signal lineshape fits are both Gaussian with a third-order polynomial to model the background. The masses and the widths of the two signals are free parameters of the fit. The uncertainty on the yield is statistical only, whereas the uncertainty on the fitted mass corresponds to a ~1 per mille uncertainty on the pT scale calibration. The plot corresponds to an integrated luminosity of around 0.24 fb-1 |

The signal lineshape fits are Gaussian with a fourth-order Chebyshev polynomial to model the background. The separations of the three peaks are fixed using the PDG masses but the absolute position on the invariant mass scale is a free parameter of the fit. The widths of the 2S and 3S peaks are fixed to that of the 1S, which is a free parameter of the fit. All uncertainties quoted are statistical The plots correspond to an integrated luminosity of around 0.24 fb-1. |
