We present a tool for the comparison and validation of the integration
packages suitable for Solar System dynamics. iCompare, written in Python,
compares the ephemeris prediction accuracy of a suite of commonly-used
integration packages (JPL/HORIZONS, OpenOrb, OrbFit at present). It integrates
a set of test particles with orbits picked to explore both usual and unusual
regions in Solar System phase space and compares the computed to reference
ephemerides. The results are visualized in an intuitive dashboard. This allows
for the assessment of integrator suitability as a function of population, as
well as monitoring their performance from version to version (a capability
needed for the Rubin Observatory’s software pipeline construction efforts). We
provide the code on GitHub with a readily runnable version in Binder
(https://github.com/dirac-institute/iCompare).
