Derived datasets & specifications

Nuclear explosions import specification (SIPRI + CMR reconciliation)
© Adrien Normier · governs the merged 1945–1998 detonation layer (dedup rules, EMP yield scaling) · dataset shipped in the registry, sources public domain
Deep-space maneuver exhaust dataset
© Adrien Normier · SHIPPED as the registry's "exhaust" layer — 106 propellant puffs located from navigation-arc discontinuities, momentum-conserving gas states, Tsiolkovsky masses · method article

Scientific basis — the models and the literature they lean on

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.

ModelSourceWhat we takeWhat 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
