# Earth and Moon orientation is from the 2009 report; the 2015 report gives no
# orientation data for either body.  Prefer framelib::ItrsFrame for the Earth
# and a binary Moon PA kernel for the Moon whenever accuracy matters.
#
# Columns.  Angles are degrees, radii are kilometres, fields are comma
# separated, and multi-valued fields are space separated and may be empty.

#   naif_id           NAIF integer body code
#   name              body name, matching planetlib::Body::name()
#   a_km b_km c_km    triaxial ellipsoid radii: two equatorial, one polar
#   pole_ra           right ascension of the north pole:
#                     deg, deg/century, deg/century^2
#   pole_dec          declination of the north pole, same units
#   pm                prime meridian: deg, deg/day, deg/day^2
#   nut_prec_ra       nutation/precession amplitudes for RA, deg
#   nut_prec_dec      nutation/precession amplitudes for declination, deg
#   nut_prec_pm       nutation/precession amplitudes for the prime meridian, deg
#   nut_prec_angles   the barycentre's nutation/precession angles, flattened
#                     into triples of deg, deg/century, deg/century^2
