Still, the paper makes a quantitative factual assertion in its abstract and Section 1: the 37-paper count. That count is the most load-bearing piece of evidence for the claimed radio-astronomy applicability, and it is only supported by an external Zenodo link not reproduced in the manuscript. The examples are real but selected, so they do not by themselves establish a rate of adoption. The proposed check directly tests the count's completeness and accuracy. I agree with the reader that the weakest assumption is the accuracy and representativeness of the 37-paper list. This concern does not change the verdict: the paper remains outside the scope of a research verdict, and its main quantitative claim is unverifiable from the text alone rather than demonstrably wrong. I therefore recommend UNCHANGED.

The three worked examples are high-profile and likely genuine, but they are selected, so they cannot by themselves establish a rate of adoption. The word 'growing' also needs a baseline, which the paper does not provide; a raw count since 2020 would look the same whether radio use is rising, flat, or falling relative to earlier years. If the Zenodo list counts papers that only cite Montage in acknowledgments, or includes non-peer-reviewed items, the quantitative headline is inflated.

The open-source, modular design argument is plausible and consistent with the cited external papers. The manuscript is short and does not present new algorithms or data, but it could serve as a useful citation record for the community. Its main value depends on the transparency and completeness of the 37-paper count, which is currently not verifiable from the paper itself.","major_comments":[{"comment":"The central quantitative claim of the paper — that Montage has found 'particular applicability' in radio astronomy with '37 peer-reviewed papers reported since 2020' — is not verifiable from the manuscript.

However, the lack of a transparent list behind the headline '37 papers' is a reproducibility issue that the authors should be able to fix easily. If the list is provided and shows consistent use across independent groups, the paper could be a useful record for the community. If the list is not provided, the quantitative claim should be removed or heavily qualified."},"author_rebuttal":null,"desk_editor":{"model":"deepseek-v4-flash","letter":"This is not a research paper and I would not referee it as one. It is a short application note from the Montage developers documenting that their mosaic engine has been used in radio astronomy, with three worked examples and a pointer to a Zenodo record listing 37 peer-reviewed papers since 2020. On its own terms it is clear, honest, and the examples are real: MeerKAT/MIGHTEE, LoTSS-DR2 Faraday tomography, and FRB host follow-up are all genuine uses and the citations check out. Credit where due: the authors say outright that the design principles are the reason for adoption, and the evidence for adoption is external papers from independent groups, not self-citation. That is the right way to make a usage claim.\n\nThe soft spots are real but proportionately minor. The headline 37-paper count is the one quantitative support for 'growing' use, and the paper does not give the list, the search strategy, or inclusion criteria; it points to an external Zenodo record. A reader cannot verify the number without leaving the paper, and 'growing' needs a baseline: a raw count since 2020 looks the same whether radio use is rising, flat, or falling. The three examples are selected and high-profile, so they show capability, not rate of adoption. That said, this is an application note, not a scientific claim machine. The central qualitative claim — Montage has seen substantial radio-astronomy uptake — is well supported by the examples and by the independent literature, so the reproducibility gap does not sink the paper.\n\nThe paper is for people who maintain or evaluate scientific software, or who want a quick citation for Montage in a radio context. It would get an honest, useful review at a software or astronomical-methods venue, and I would send it to one with a request: put the list of 37 papers, or at least the search criteria, in the text or an appendix instead of only in Zenodo, and say what 'since 2020' is relative to. That would close the only real gap. I would not desk-reject it, but I would not call it a research contribution either.","headline":"A clean, honest software-adoption note whose headline claim is probably right, but the 37-paper count is unverifiable from the text and 'growing' has no baseline.","tokens_in":5143,"tokens_out":1324,"would_cite":true,"duration_ms":17001,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"This paper documents that Montage, a 22-year-old open-source mosaic engine, has been used in 37 peer-reviewed radio astronomy papers since 2020 and argues its modular design is why it keeps being adopted.","keywords":["Montage","image mosaicking","radio astronomy","SKA precursors","MeerKAT","LOFAR","fast radio bursts","open source software"],"falsifier":"Audit the Zenodo record (https://zenodo.org/records/14226692) and verify that each of the 37 papers actually uses Montage in its data-processing methods; if most use it only incidentally or not at all, the evidence for broad radio-astronomy adoption collapses.","tokens_in":4252,"feed_emoji":"📡","tokens_out":5860,"duration_ms":53832,"temperature":0.7,"pith_summary":"The paper argues that Montage, the open-source mosaic engine released in 2002, has become a widely used tool in radio astronomy because its modular design makes it easy to drop into existing pipelines. As evidence, it reports 37 peer-reviewed papers since 2020 that used Montage, and it describes three high-profile applications: mosaicking MeerKAT and Murchison Wide-field Array observations through the CARACal pipeline, building a Faraday cube from LOFAR LoTSS-DR2 data for rotation-measure synthesis, and coadding follow-up images of fast radio burst host galaxies. The claim matters because it shows a general-purpose, spectrum-agnostic toolkit can survive and thrive across changing telescope generations.

This modularity is what lets external pipelines such as CARACal's MosaicQueen call Montage components for two- and three-dimensional mosaics and primary-beam correction, which is the mechanism behind the radio-astronomy uptake. The paper's argument is that the design, not any particular algorithm, is the load-bearing reason for the engine's longevity and cross-spectrum applicability.","core_discovery":"The paper's central claim is that Montage's design as an open-source ANSI-C toolkit with independent components for each step of mosaic creation, plus support for all WCS extensions, is the principal reason for its 22-year lifetime and its adoption in radio astronomy. It asserts that 37 peer-reviewed papers since 2020 have used Montage, and it highlights three science applications where the engine carried the mosaicking work: SKA precursor surveys with MeerKAT and the Murchison Wide-field Array, Faraday tomography of LoTSS-DR2 data to map the local interstellar medium, and identification of fast radio bursts through coadded host-galaxy images.
