Proton reconstruction with the Precision Proton Spectrometer (PPS) in Run 2

The Precision Proton Spectrometer (PPS) has collected more than 110 fb$^{-1}$ of data over the course of the LHC Run 2. This note illustrates the key features of PPS alignment and optics calibrations developed during this period, the reconstructed proton distributions and performance of the PPS simulation. The reconstruction and simulation are validated using a sample of (semi-)exclusive di-lepton events.
