aetherfield 0.2.0

AetherField runtime ephemeris

AeTherField Staging

This folder stages a future standalone package for AetherField — a Skyfield-free runtime ephemeris model that uses learned calibration/piecewise drift and offers simple APIs for signs, longitudes, alignments, phases, and (now) sunrise/sunset estimation.

Plan

• Extract reusable runtime core from the root aetherfield.py.
• Preserve public APIs: aether_longitude, aether_sign, aether_alignments, moon_phase.
• Add sunrise_sunset(zone, coords, date, depression_deg) for Moontime temporal hours.
• Keep calibration loaders and CLI tools in a tools subpackage.
• Console scripts (staging): aetherfield-compare, aetherfield-benchmark, aetherfield-calibrate-all.

Local Layout (staging)

• src/aetherfield_pkg/ — package source (to be populated)
• pyproject.toml — packaging config (setuptools)

Dev Tips

• Create a venv and install local deps from the project root as usual.
• In staging, the package may re-export from the root aetherfield.py to avoid duplication.

CLI Usage (staging)

• Compare a single timestamp: python -m aetherfield_pkg.cli.compare --body mars --dt 2025-06-21T12:00:00Z
• Benchmark a range: python -m aetherfield_pkg.cli.benchmark --start 2001-01-01T00:00:00Z --end 2001-12-31T00:00:00Z
• Calibrate all: python -m aetherfield_pkg.cli.calibrate_all --out aetherfield_calibration.json
