Derived datasets, working documents and the scientific basis of the models used around the registry. Project licences: SSR-GPL v2.0 · CFS public-interest grant.
Every estimating model in the system (the factory, and the physically-scaled visuals) is anchored on published work. The honest framing matters more than the citation: the right column states what we do not claim. Estimated values always render as estimates and carry their method in the inspector.
| Model | Source | What we take | What we do NOT claim |
|---|---|---|---|
| Exoplanet mass ↔ radius completion (factory LIGHT) | Chen & Kipping 2017, Probabilistic Forecasting of the Masses and Radii of Other Worlds, ApJ 834:17 — simplified power-law regimes | Point estimates across the Terran/Neptunian/Jovian regimes when the catalog gives only one of mass/radius | No posterior, no uncertainty band; a class trend applied to one object — rendered translucent, listed per object |
| Landing plume deposition footprint (factory LIGHT) | Shipley, Metzger & Lane 2014, Lunar Cold Trap Contamination by Landing Vehicles, NASA doc 20140017853 (KSC plume tools) | The ballistic character of exhaust on airless bodies; footprint scale ≈ (v²/g)·√(m/15 t) with v ≈ 1 km/s for the deposited tail, anchored on the Apollo-LM class and scaled by the catalogued lander mass | An upper ENVELOPE of where plume gas can reach — NOT the visible scar (LRO-observed disturbance halos are orders of magnitude smaller); no deposited-mass field, no engine-specific physics (v is a class value), no real approach azimuth (seeded, declared); bodies with atmospheres are excluded — the model declines rather than guesses |
| Detonation departure visuals (mushroom) | Glasstone & Dolan 1977, The Effects of Nuclear Weapons — empirical cloud-top / fireball fits, anchored on Hiroshima, Castle Bravo, Tsar Bomba | Yield-scaled cloud height (≈6 750·Ykt0.212 m, mesosphere cap) and fireball radius for a 1-second staging | Not an effects model: no blast, thermal or fallout physics — a physically scaled VISUAL of the moment |
| Exoatmospheric burst visuals | Starfish Prime observation record (1962, DNA summaries; Glasstone §2.52+) | Debris-sphere scale and the white → auroral-violet phenomenology (no mushroom in vacuum) | Same: visual staging only |
| EMP source powers (nuclear-tests layer) | Yield scaling anchored on the Starfish Prime record (import specification © A. Normier) | Per-shot EMP emission records, exo/surface branches | Powers are MODELLED and labeled so — no claim of measured spectra |
| Maneuver exhaust dataset | Tsiolkovsky rocket equation; storable-bipropellant exhaust velocity class (~3.1 km/s); JPL Horizons navigation arcs | Δv detection at arc boundaries, momentum-conserving gas states, propellant masses | Upper-bound PROXIES, not a burn list — yearly arcs aggregate perturbation residue; ve is a class median (see the declared limits) |
| Galactic field stars (factory FILL) | NASA/JPL-Caltech R. Hurt structure map (Spitzer/GLIMPSE-informed artist concept); R0 = 8.1 kpc (GRAVITY Collaboration class); flat 220 km/s rotation | Density and population-color sampling of the map; bulge-thickened scale heights; flat-curve drift | NOT a stellar census: an artist-informed structure map sampled into SYNTHETIC points (tagged and dimmed as such). Real stars come from Gaia DR3 |
| Star surface tint | Blackbody → sRGB numerical fit (T. Helland) on catalogued Teff | Display color of the animated sun material | Display only — no spectrophotometry |
| EM detection ranges | Band-noise table for current human instruments; parameterized photon limit (1 km² aperture, 1 000 s, η = 0.5) for the ETI bound | Boresight ranges r = √(EIRP / 4πS·Δf) shown per emission | Assumption-laden by construction — the parameters are printed next to every figure (MODELLED) |
| Transmission gap-filling (factory LIGHT) | Documented METI record medians (Zaitsev 2006 class: S/C-band carriers, 10²–10³ kW, 64 m apertures) | Statistically relevant figures for catalogued transmissions whose physics the source omits | Nothing invented for events without dates or physics: those render as events WITHOUT emission specs |
