iCompare

Aims:

There are 4-5 integrators that everyone uses in Solar System dynamics that have never been fully compared and tested:

• OpenOrb
• FindOrb
• OrbFit
• JPL Horizons
• ADAM

We’d like to create an automated piece of code that propagates asteroids using all these integrators, compares their outputs, and presents it in some visually understandable way (e.g., a colourcoded matrix w. the asteroid on the Y axis and the integrator on the X axis).

More documentation will appear relative to completion rate.

Currently available integrators

• OpenOrb using pyoorb (python bindings of OpenOrb)
• OrbFit via a Python wrapper that calls the OrbFit command-line code

Currently available functionality

• receive ephemerides comparison via great circle distance in the form of a table
• provide any asteroid or list of asteroids and receive visual comparison

Future functionality

• parallelizing of code for asteroid lists
• addition of FindOrb to integrator suite
• please submit requests via pull request

Requirements

• installation of OpenOrb and OrbFit, see here for OpenOrb: https://github.com/oorb/oorb, and here for OrbFit: http://adams.dm.unipi.it/orbfit/
