IceTracks-DR2: IceCube Neutrino Candidate Events for Point Source Searches, 2008-2022

IceCube Collaboration's IceTracks-DR2 release contains track-like neutrino candidate events detected between April 2008 and May 2022. This 14-year sample is the event set used for IceCube's time-integrated neutrino point source searches and supersedes the previous 10-year release. The data includes reconstructed particle information, detector uptime logs, and Monte Carlo simulation response files for modeling point sources.

Use Cases

• Searching for neutrino point sources based on reconstructed particle information and direction.
• Analyzing notable astrophysical neutrino source candidates like NGC 1068 and TXS 0506+056 using the standardized event sample.
• Modeling detector response to arbitrary point sources using the provided Monte Carlo simulations and effective areas.
• Conducting time-integrated analyses of neutrino data across 14 years of detector operation.

Strengths

• Covers 14 years of data from April 2008 to May 2022, providing a long temporal baseline.
• Includes four additional years of data and improved calibrations compared to the previous IceTracks-DR1 release.
• Provides complementary data files including detector uptime logs and instrument response functions for analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is not intended for use in diffuse astrophysical spectral analyses, limiting its scope.
