An offline-capable, interactive all-sky atlas of every system with a published image of a circumstellar disk (mm/submm/cm interferometry, high-contrast scattered light / thermal IR, far-IR single-dish — resolved or unresolved, detections or imaged non-detections), a directly imaged planet or substellar companion, or a coronagraphically imaged quasar host. Click any object on the sky map to browse its images across instruments, wavelengths and epochs, with clickable arXiv / SciX citations for every image.

747 systems · 3172 image records, every one a panel cropped from a peer-reviewed figure with full citations; coordinates for every system; a companion catalogue with per-object status (confirmed / candidate / disputed / refuted). python3 backend-data/build.py prints the exact live counts — trust it over any number in prose. Session-by-session history lives in docs/HISTORY.md.

The viewer offers three views — Sky map, Coverage matrix, and Tonight (an observability planner with per-target airmass.org night-chart links and CSV export) — with faceted filters (wavelength band, facility, instrument, missing modality), a light/dark theme, and a 12-language UI (including right-to-left Arabic and translated constellation names). Everything runs client-side from file:// — no server, no build step, no CDN. See frontend/README.md for the full feature map.

Contributions are very welcome — new systems, missing instruments/epochs, coordinate or citation fixes, translations, frontend improvements — whether you edit by hand or drive an AI agent on your own machine (most of the atlas was built that way). Fork, make your change, and open a pull request; to just suggest a paper or target, open an issue.

• Read CONTRIBUTING.md for the full recipe (human and agent-driven).
• Using an agent? AGENTS.md (and CLAUDE.md for Claude Code) auto-loads in most harnesses and orients it the moment you open the repo.

Two rules for any PR: python3 backend-data/validate.py must report 0 errors, and never hand-edit the generated frontend/data.js (rebuild with python3 backend-data/build.py).

index.html          ← THE app. Open this. (loads frontend/ + images/)
frontend/           ← app.js, style.css, data.js (data.js is GENERATED — do not hand-edit)
data/               ← the database: one JSON per system + docs. THIS is what you edit.
backend-data/       ← Python pipeline: seed → coordinates → crop → validate → build
images/             ← _sources/ (downloaded figures) + <system_id>/*.png (cropped panels)

Every folder has its own README.md. Agents: CLAUDE.md / AGENTS.md route you to the one doc your task needs; HANDOFF.md is the complete handbook.

Scope widened 2026-07-16: the atlas is a comprehensive compendium of published images of circumstellar disks (resolved or unresolved, detections or imaged non-detections), directly imaged companions (including candidates and refuted candidates), and coronagraphically imaged quasar hosts. The former "≥ a few resolution elements" bar is retired. Canonical criterion: data/README.md → Inclusion criterion.

• Disks: any published sky-image panel of a circumstellar disk — protoplanetary (incl. transition, edge-on, eruptive-star and Class 0/I embedded), debris, and Orion proplyd silhouettes — from mm/submm/cm interferometers (ALMA, SMA, PdBI/NOEMA, VLA, CARMA, OVRO, BIMA, ATCA), scattered light / thermal IR (HST, JWST, GPI, SPHERE, Subaru HiCIAO/SCExAO, NACO, MagAO(-X), LBTI, …), VLTI reconstruction, and far-IR/submm single-dish (Herschel/Spitzer/JCMT/CSO). Unresolved point sources and imaged non-detections are in scope; the disposition is stated plainly on the record (e.g. "unresolved point source", "1.3 mm continuum non-detection").
• Companions: directly imaged planets and brown-dwarf companions, including published candidate and refuted-candidate panels (status confirmed/candidate/disputed/ refuted tracked per companion). Must be genuine imaging/interferometric panels — not a transit light curve, RV curve, SED, or photometry point.
• Quasar hosts: coronagraphic / PSF-subtracted host-galaxy imaging (redshift instead of dist_pc).
• Excluded (not sky images): contrast curves, radial profiles, SEDs, visibility fits, channel-map grids, PV diagrams, model predictions, and press-release images. Every image is cropped from a peer-reviewed figure and linked to its paper (arXiv + SciX).

Three parts, three answers:

• Code (index.html, frontend/ JS+CSS, backend-data/ Python): MIT — see LICENSE.
• Compiled database (data/systems/*.json, the metadata in generated frontend/data.js): CC BY 4.0 — see LICENSE-DATA.md. Cite this repository (and the accompanying paper, once published) when reusing.
• Images (images/**/*.png): not covered by either license. They are low-resolution crops of figures from peer-reviewed papers — cropped from the authors' own arXiv source files (preprint figures), not from the journal-typeset articles. Rights remain © the original authors (and the journals for the published versions — AAS, A&A, MNRAS, …); each crop is reproduced here with a per-image credit line and full citation for scholarly reference. Follow each record's links (arXiv / SciX / DOI) for the originals and for any reuse permissions.

diskatlas is a non-commercial, not-for-profit resource created solely for scientific research and education. The image excerpts are small, reduced-resolution crops taken from the authors' own arXiv source files (preprint figures) — not from the journals' typeset versions of record — to help researchers locate and navigate the primary literature. Every excerpt carries a credit line and links back to the original paper (arXiv / SciX / DOI), and is not a substitute for the published article. We believe this constitutes fair use (17 U.S.C. § 107) / fair dealing for purposes of research and scholarship.

We have no intention to infringe any copyright. All rights in the original figures remain with their authors (and, for the versions of record, their publishers). If you are a rights holder and would prefer that a particular image not appear here, please open an issue and it will be removed promptly.
