Upgrades to the LHCb computing infrastructure in the first long shutdown of the LHC have allowed for high quality decay information to be calculated by the software trigger making a separate offline event reconstruction unnecessary. Furthermore, the storage space of the triggered candidate is an order of magnitude smaller than the entire raw event that would otherwise need to be persisted. [...]

The performance of the muon identification in LHCb is extracted from data using muons and hadrons produced in $J/\psi \to \mu^+ \mu^-$, $\Lambda ^0 \to p\pi^-$ and $D^{\star +} \to \pi^+ D^0(K^- \pi^+)$ decays. The muon identification procedure is based on the pattern of hits in the muon chambers. [...]
