Description
The IceCube Neutrino Observatory is a cubic-kilometer-scaled detector located at the Geographic South Pole. The calibration of the directional reconstruction of neutrino-induced muons and the pointing accuracy of the detector has to be verified. For these purposes, the moon is used as a standard candle to not rely exclusively on simulated data: Cosmic rays get absorbed by the moon, which leads to a deficit of cosmic-ray-induced muons from the lunar direction that is measured with high statistics. The Moon Shadow Analysis uses an unbinned maximum-likelihood method, which has been methodically improved, and uses higher statistics and a larger detector compared to previous analyses. This allows to observe the shadow with a large significance per month. It also enables an experimentally-based testing of analysis methods and directional muon reconstruction algorithms.
