# Colors are mainly derived from B-V and V-R indices, most of which
# come from the MBOSS compilation: http://www.eso.org/~ohainaut/MBOSS/
# and converted using FarGetaNik's color calculator:
# https://docs.google.com/spreadsheets/d/1_mMXYzeYE4JcXJFrn4j5XWJvf2ik13r8v1BZ7G9I4EY/
# Centaur colors are derived from SMASS spectra and converted
# to RGB values using Matt Wronkiewicz's spectrum2rgb utility
# that is distributed with the Celestia source package.
# Orbits for satellites have been taken from Emelyanov & Drozdov (2020), MNRAS 494 (2), 2410
# "Determination of the orbits of 62 moons of asteroids based on astrometric observations."
# with exceptions being listed as comments over this file.
# In cases where the system barycenters have been defined as ReferencePoints, the
# mass ratios (and thus relative semi-major axes) have been computed from the cube of
# the component sizes, under the assumption of equal densities for both of them.
