Date: Fortnight of Renewal (Dawning), day 8 (FR 8)
Sky Solara Vaelus
Relative Solar Inclination (Δ): +2.50° (Closing)
Seasonal Equatorial Inclination (barycenter): -8.00°

param meaning default
size max stage width (px) 768
fps play speed (frames/s) 5
wobble solar relative wobble amplitude (Δ, degrees) 2.5
equator seasonal/barycenter max tilt (degrees) 8
sep visible horizontal separation between suns (degrees) 2.5
degpx vertical degree→pixel scale (px per degree) 10
