Celestial partitioning frameworks are not abstract mathematical exercises; they purport to calculate with precision the physical position of empty zodiacal/ecliptic coordinates and celestial bodies relative to the local horizon. With the advent of modern astronomical engines, we are no longer required to debate the geometry of house division—we can directly observe the physics.
Available today via Caelum Stratagem, The Master Stellarium-SFG Manual provides a complete, step-by-step software exercise and modular JavaScript library for verifying the spatiotemporal fidelity of any house system using Stellarium and Solar Fire Gold in unison.
Key contents of the manual include:
- Environmental & Local Horizon Calibration
Exact procedural steps to activate Stellarium’s Ecliptic of Date (employed by Swiss Ephemeris by default) and produce the unrefracted mathematical horizon (as utilized by the Swiss Ephemeris).
- The Master Spatiotemporal Command
An automated horizon-hunting JavaScript routine that locks onto any target zodiacal/ecliptic coordinate at its exact millisecond of Geometric Rise (00°00’) and extracts its Altitude (height) and Azimuth (direction) across every 1/6 interval of its diurnal arc (or 1/3 of its diurnal semiarc).
- Empirical Exhibits (The Kodiak Table & The Angular Confession)
Side-by-side trajectory tables demonstrating how natural non-linear partitioning (Ptolemy/Placidus) preserves the coordinate’s identity across its entire diurnal journey, whereas linear division methods (e.g., Alcabitius, Campanus, Regiomontanus, Koch, Polich-Page) attempt to solve a differential problem (i.e., the non-linear rate of change in altitude and azimuth) by relying upon Euclidean fractions—losing track of the physical coordinate in the intermediate quadrants before snapping back abruptly to it at the primary axes (the sole instance where they respect the obliquity/declination of said coordinate).
- Modular Script Library
Standalone diagnostic scripts for manual temporal stepping and instant Alt/Az extraction of any empty zodiacal/ecliptic degree at a certain time and place.
