Service Documentation

This data set is a list of neutrino candidate events recorded by the AMANDA-II neutrino telescope during the period 2000-2006. The events are mostly from atmospheric neutrinos with a typical energy of several hundred GeV. The events include a small fraction of misreconstructed cosmic ray muon tracks, where this contamination increases near the horizon.

Included are the right ascension, the declination and the angular resolution (in degrees) for each event. Also included are the number of modules hit (in the experiment's jargon referred to as the number of channels, Nch), a quantity that provides a rough measure of the energy of the event, and the Modified Julian Day (MJD). The accuracy of the MJD values is one second.

The final column is a flag indicating the subset of events used in the seven-year atmospheric neutrino analysis: R. Abbasi et al., Phys. Rev. D79, 102005 (2009). In order to further reduce background contamination due to atmospheric muons, this analysis imposes additional quality criteria, for instance, a restricted declination and Nch range.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
