points of the apparatus which emit short light pulses through the water [@OBs]. This allows a sub-nanosecond accuracy on the relative timing [@timing]. Additional information on the detector can be found in Ref. [@antares].

Data-taking started with the first 5 lines of the detector installed in 2007. The full detector was completed in May 2008 and has been operating continuously ever since, except for some short periods in which repair and maintenance operations have taken place. Other physics results using this data-taking period can be found elsewhere [@diffuse; @monopole; @nuosc; @ps; @grb; @atmnu; @dmsun; @fermibub; @pe].

High-energy muon neutrinos interacting in the matter before the detector produce relativistic muons that can travel hundreds of metres and cross the detector or pass nearby. These muons induce Cherenkov light when travelling through the water, which is detected by the OMs. From the time and position information of the photons provided by the OMs, the direction of the muons, which is well correlated with that of the neutrinos, is reconstructed.
