Benchmark

Compare accuracy and performance with famous astronomy libraries and tools like:

• Skyfield
• Astropy
• IMCCE
• NASA JPL Horizons
• astroplan

Data

• Better support of time scales
• Better support of coordinate systems (geocentric, heliocentric, barycentric, ICRF)
• Better support of corrections (nutation, precession, light-time, relativistic)
• Observation events of planets
• Integrate Messier catalogue
• Integrate the New General Catalogue
• Integrate the Bright Stars Catalogue
• Integrate constellations
• Tool to prepare observations for given date, location and parameters
• Predict eclipses general and local circumstances

Models

• Integration of the DE Series (Jet Propulsion Laboratory Development Ephemeris)
• or, integration of INPOP (Intégrateur Numérique Planétaire de l'Observatoire de Paris)
• Integration of ELP2000-82

Documentation
