IceCube Second Track Data Release IceTracks-DR2: Data from 2008-2022 for Neutrino Source Searches

The pith
IceCube releases its most sensitive public muon track dataset covering 14 years of observations.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The IceCube Second Track Data Release provides 14 years of muon track data for neutrino source searches, featuring an updated event selection and improved detector calibration for data after June 2010. This release includes binned instrument response functions and effective areas, and internal analyses confirm it offers higher sensitivity than prior versions.
What carries the argument
Updated event selection and improved detector calibration for post-June 2010 data that enhance sensitivity to neutrino point sources.
If this is right
- Users can conduct more sensitive searches for both steady and transient neutrino sources.
- Public benchmarks allow verification of analysis results with open software.
- Community searches will benefit from the extended observation period and refined processing.
- Comparisons validate the public binned functions against internal tools.
Where Pith is reading between the lines
- This could enable tighter limits on the locations of cosmic neutrino accelerators when combined with other wavelengths.
- Adoption might reduce systematic differences between different analysis groups using IceCube data.
- Longer baseline data could help in studying time variability in potential sources.
Load-bearing premise
The updated event selection and improved detector calibration applied to post-June 2010 data correctly increase sensitivity and do not introduce unaccounted systematic biases that would affect point-source searches.
What would settle it
Demonstration that searches using the new release do not achieve higher sensitivity than the prior 10-year dataset or discovery of significant biases in the new calibration would challenge the central claim.

read the original abstract
We present IceCube's latest release of muon track data for neutrino point-source searches, extending the previously published 10-year dataset to cover 14 years of observations (April 6, 2008 - May 23, 2022). This release features an updated event selection and improved detector calibration for data recorded after June 1, 2010. The release also includes binned instrument response functions and effective areas, enabling the community to perform sensitive searches for steady and transient neutrino sources. We report on key science results obtained with this dataset using internal IceCube analysis tools and compare them to those derived from analyses based on the binned response functions included in this public release. To facilitate reproducible research, we provide benchmark results obtained using this data release and publicly available software. This release represents IceCube's most sensitive and comprehensive publicly available all-sky muon track dataset to date and should be preferred over previous releases.

Referee Report
Summary. The manuscript presents IceCube's IceTracks-DR2 data release, extending the public muon-track dataset for neutrino point-source searches from 10 to 14 years (April 2008–May 2022). It incorporates an updated event selection and improved detector calibration applied to post-June 2010 data, supplies binned instrument response functions together with effective areas, reports benchmark results obtained with internal IceCube tools, and compares those results to analyses performed with the released binned responses. The authors state that this constitutes the most sensitive and comprehensive publicly available all-sky muon-track sample and should be preferred over earlier releases.
Significance. If the updated selection and calibration are correctly implemented without unaccounted biases, the release materially improves the sensitivity and reproducibility of community searches for steady and transient neutrino sources. The provision of binned response functions and effective areas, together with explicit internal-versus-public comparisons and benchmark results, directly supports independent use of the data and strengthens the claim that this dataset should supersede prior public releases.
minor comments (2)
- [Abstract and §1] The abstract and introduction refer to 'publicly available software' for the benchmark results; adding explicit names, version numbers, and repository links would improve reproducibility.
- [Figures 2–4 and Tables 1–2] Figure captions and table headers should explicitly state the energy and angular binning used for the released response functions so that users can immediately assess compatibility with their analysis codes.
Simulated Author's Rebuttal
We thank the referee for their positive review of the manuscript, their assessment of its significance for the community, and their recommendation to accept. No major comments were raised in the report.
Circularity Check
Data release with no load-bearing circular derivation
full rationale
This is a standard data-release paper extending the muon-track sample, supplying binned response functions and effective areas, and reporting benchmark comparisons between internal and public analyses. The central claim (most sensitive public all-sky track dataset) rests on direct provision of the data and response functions rather than any fitted parameter renamed as a prediction or any self-citation chain that substitutes for independent verification. External users can reproduce or falsify the sensitivity comparisons using the released material, satisfying the criteria for non-circularity (score 0-2). No self-definitional, fitted-input, or uniqueness-imported steps appear in the described chain.
Axiom & Free-Parameter Ledger
axioms (1)
- domain assumption IceCube detector response and calibration procedures for data after June 2010 are accurate and improve event selection without new biases.
