The pith
The effective number of active PMTs provides criteria to group compatible runs in the ANTARES detector.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
In this note we describe effective criteria to group compatible runs based on the effective number of active PMTs in each run. This allows events from various periods in the year to be summed together taking care of the various environmental conditions and detector configurations.
What carries the argument
The effective number of active PMTs, used as a numerical indicator of detector configuration to select compatible runs for data combination.
If this is right
- Runs can be selected and summed across the year while preserving consistency in environmental and hardware conditions.
- Larger combined datasets become available for muon track reconstruction without mixing incompatible periods.
- A single numerical threshold on active PMTs offers a straightforward operational tool for long-term data handling.
- Rate monitoring of down-going muons can proceed on grouped samples that reflect stable detector response.
Where Pith is reading between the lines
- The same active-sensor count approach might apply to run selection in other large neutrino telescopes facing similar configuration changes.
- One could test the groups by checking whether reconstructed muon properties remain uniform within each group across independent observables.
- Correlating the effective PMT number with specific factors such as water clarity or biofouling could refine the criterion further.
Load-bearing premise
The effective number of active PMTs provides a sufficient measure of run compatibility under varying environmental conditions and detector configurations.
What would settle it
A clear mismatch between runs that share nearly the same effective PMT count but display substantially different down-going muon rates would show the criterion fails to capture true compatibility.
read the original abstract
Large underwater telescopes have been proposed as a challenging method to measure high energy neutrinos from astrophysical objects. In recent years, The Antares collaboration has designed and realized the first detector of this type in the Mediterranean Sea. Muon tracks produced by the neutrino interaction in the surrounding medium are reconstructed from the arrival time and the number of photo-electrons of the Cherenkov light measured by the Photomultiplier tubes (PMT) array of the detector. In order to provide sufficient statistics, the events from various periods in the year must be summed together taking care of the various environmental conditions and detector configurations. In this note we describe effective criteria to group compatible runs based on the effective number of active PMTs in each run.

Referee Report
Summary. The manuscript is a short note on the ANTARES underwater neutrino telescope. It explains that muon tracks are reconstructed from PMT arrival times and photo-electron counts, and that events from different periods must be combined while accounting for varying environmental conditions and detector configurations. The central claim is that effective criteria can be defined to group compatible runs using the effective number of active PMTs in each run.
Significance. If the criteria turn out to be well-defined, reproducible, and validated against actual data, the note could provide a practical tool for standardizing run selection in ANTARES analyses, thereby improving the reliability of summed high-energy neutrino statistics. The approach is presented as a direct operational definition rather than a derived model, which avoids obvious circularity, but the lack of any explicit formula, test, or metric in the available text prevents a full evaluation of its utility.

- [Abstract] Abstract: the text states the intent to 'describe effective criteria' based on the effective number of active PMTs but supplies neither the definition of this quantity, the grouping algorithm, any validation tests against environmental or configuration variables, nor performance metrics. Without these elements the central claim cannot be assessed for soundness or load-bearing status.

Authors: We agree that the submitted abstract is too brief and does not include the requested elements. The manuscript is a short note whose current text only announces the approach without elaboration. In the revised version we will expand the abstract to define the effective number of active PMTs, outline the grouping algorithm, summarize validation tests against environmental and configuration variables, and report performance metrics. This will make the central claim assessable while preserving the note's concise character. revision: yes
Circularity Check
No significant circularity; operational definition without derivation chain
full rationale
The document consists only of an abstract describing criteria to group compatible runs based on the effective number of active PMTs. No equations, derivations, predictions, or first-principles results are present that could be inspected for reduction to inputs by construction. The method is framed as a direct operational definition tied to detector status, rendering the claim self-contained with no load-bearing steps that invoke self-definition, fitted inputs renamed as predictions, or self-citation chains.
