Performance study of track and energy reconstruction in IceCube

The IceCube Neutrino Observatory is the World largest neutrino telescope located at the South Pole. It instruments one cubic kilometer of Antarctic ice with 5160 optical modules (DOMs) at a depth of about 1500 m to 2500 m. IceCube found evidence for astrophysical neutrinos but still their sources remain hidden. Muons created in charged-current neutrino interactions give good reconstruction accuracy for the search of neutrino sources. Current analyses in IceCube, such as for instance the point source analysis, consist of several different methods to reconstruct the angular direction and resolution and the energy of track-like secondary muons. This talk presents the performance of two different event reconstructions and an estimation of their uncertainties.
