The pith
AstroInspect is a web-based system that lets users upload galaxy catalogs by coordinates and automatically pulls imaging, spectra, and photometry from SDSS, Legacy Surveys, and S-PLUS for visual inspection.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
AstroInspect is a web-based system that provides an intuitive graphical user interface for uploading catalogs of objects defined by celestial coordinates and automatically enriching them with complementary imaging, spectroscopic, and photometric data retrieved in real time from surveys such as SDSS, the Legacy Surveys, and S-PLUS. The system supports efficient visual inspection workflows for tasks including classification, catalog refinement, and validation of automated methods. As a concrete demonstration, the authors applied AstroInspect to a candidate set of 981 galaxies selected from S-PLUS data within a 7-degree radius of the Hydra I cluster and produced a catalog of 80 galaxies with Hα
What carries the argument
The AstroInspect graphical user interface, which accepts coordinate-based catalogs and performs real-time retrieval and display of multi-survey data to support direct visual assessment.
If this is right
- Users can complete visual inspection tasks on a single platform instead of switching between separate survey websites and tools.
- The integrated view supports rapid refinement of candidate lists, such as identifying emission-line galaxies from photometric selections.
- The approach scales to larger catalogs by reducing the time spent on data gathering before inspection begins.
- Results from the Hydra I example show the system can produce usable scientific catalogs from hundreds of candidates in a defined sky region.
Where Pith is reading between the lines
- Wider use could make visual classification outputs more comparable across different research groups by standardizing the data presented to each inspector.
- The same interface could be extended to other object types or wavelength regimes once additional surveys are linked.
- If the tool were combined with simple pre-filters, it might lower the total number of objects that still require human review.
Load-bearing premise
Real-time data retrieval from the external surveys will stay reliable and complete while user visual inspections produce consistent classifications without reported measures of agreement or error.
What would settle it
A session in which data from SDSS or S-PLUS fails to load for a known object, or a test set of objects inspected independently by several users that shows low agreement on H-alpha presence.
read the original abstract
The rapid growth of imaging and spectroscopic surveys has intensified the need for efficient tools that support visual inspection, a practice that remains essential for tasks such as classification, catalog refinement, and validation of automated methods. Existing solutions, however, often require the use of multiple platforms and complex workflows to integrate heterogeneous data. To address this challenge, we present the first release of the AstroInspect (https://astroinspect.github.io), a web-based system which ensures seamless access to several astronomical resources. The system provides an intuitive graphical user interface (GUI) through which users can upload catalogs of objects defined by celestial coordinates. AstroInspect automatically enriches these catalogs with complementary information, including imaging, spectroscopic, and photometric data retrieved in real time from surveys such as the Sloan Digital Sky Survey (SDSS), the Legacy Surveys (LS), and the Southern Photometric Local Universe Survey (S-PLUS). As an example of its scientific utility, we used AstroInspect to identify H$\alpha$ emission-line galaxies within a 7 deg radius in the direction of the Hydra I cluster (also known as Abell 1060) by visual inspection. Using a candidate set of 981 galaxies selected from S-PLUS photometric data, we produced a catalog of 80 galaxies with confirmed H$\alpha$ emission. These results highlight the potential of AstroInspect to support efficient visual inspection workflows.

Referee Report
Summary. The manuscript presents the first release of AstroInspect, a web-based GUI tool that accepts user-uploaded catalogs of celestial coordinates and automatically retrieves and displays complementary imaging, spectroscopic, and photometric data in real time from public surveys including SDSS, the Legacy Surveys, and S-PLUS. The central demonstration applies the system to visually inspect 981 S-PLUS photometric candidates within a 7-degree radius of the Hydra I cluster, yielding a catalog of 80 galaxies identified as having Hα emission.
Significance. If the described real-time integration and GUI function as claimed, AstroInspect provides a practical, unified interface that reduces the workflow friction of switching between separate survey archives and viewers. The concrete production of an 80-object Hα catalog from public data supplies a tangible, reproducible example of scientific utility; however, the lack of any quantitative performance metrics or external validation limits the strength of claims about efficiency gains or classification reliability relative to existing tools.
major comments (2)
- [Use-case demonstration] Use-case demonstration (abstract and results section): The production of the 80-galaxy Hα catalog is reported without any quantitative metrics on visual-classification accuracy, inter-rater reliability, completeness, or false-positive rate, nor any comparison against automated line-emission classifiers or prior catalogs. This omission is load-bearing for the claim that the tool supports reliable scientific catalog refinement.
- [System description] System description: The manuscript asserts seamless real-time enrichment from external surveys but contains no discussion of fallback behavior, latency handling, or completeness when queries to SDSS, LS, or S-PLUS return partial or null results. This directly affects the central claim of reliable, seamless access.
minor comments (2)
- [Abstract] The GitHub Pages URL is given without a version tag or access date, reducing reproducibility of the exact interface evaluated in the paper.
- [Introduction] A short table or paragraph comparing AstroInspect’s feature set (real-time multi-survey overlay, coordinate-based upload) to established viewers such as Aladin Lite or the SDSS SkyServer would better situate the contribution.

Referee: [Use-case demonstration] Use-case demonstration (abstract and results section): The production of the 80-galaxy Hα catalog is reported without any quantitative metrics on visual-classification accuracy, inter-rater reliability, completeness, or false-positive rate, nor any comparison against automated line-emission classifiers or prior catalogs. This omission is load-bearing for the claim that the tool supports reliable scientific catalog refinement.
Authors: We agree that no quantitative validation metrics are provided for the 80-galaxy sample. The manuscript frames this catalog explicitly as an illustrative demonstration of AstroInspect's workflow for visual inspection of S-PLUS candidates, not as a validated scientific catalog. The abstract and results emphasize support for efficient inspection rather than classification reliability or completeness. To prevent misreading, we have revised the results section to state that the sample is presented for demonstration purposes only and that users must conduct their own validation for any scientific application. Adding new metrics such as inter-rater reliability would require a separate study outside the paper's scope. revision: partial

Referee: [System description] System description: The manuscript asserts seamless real-time enrichment from external surveys but contains no discussion of fallback behavior, latency handling, or completeness when queries to SDSS, LS, or S-PLUS return partial or null results. This directly affects the central claim of reliable, seamless access.
Authors: We concur that robustness details were omitted. The revised manuscript now includes a dedicated paragraph in the System Description section covering these aspects: failed or partial queries trigger user notifications with retry options and proceed using available data; typical per-object latency ranges from sub-second to several seconds depending on network conditions and survey response; and completeness is inherently limited by the sky coverage and data availability of the queried surveys, which is indicated in the interface. These additions clarify the practical reliability of the real-time enrichment without changing the core functionality. revision: yes
Circularity Check
No significant circularity
full rationale
The paper is a descriptive software release note that presents AstroInspect as a web interface for real-time multi-survey data enrichment and demonstrates its use by producing an 80-galaxy Hα catalog from 981 S-PLUS candidates. No equations, fitted parameters, predictions, or derivation chains appear in the provided text. The central claim rests on external public surveys and user visual inspection rather than any self-referential construction, self-citation load-bearing step, or renaming of known results. The work is therefore self-contained against external benchmarks with no reduction of outputs to inputs by definition.
