The dust particle data are provided for dust instrument (SDC) calculations. The reference frame for all quantities is the Earth Mean Equator, dynamical equinox of epoch J2000 (NAIF/SPICE name = 'J2000') frame. The heliocentric Z-component of the dust particle, in the Earth Mean Ecliptic and Equinox of the Epoch J2000 (NAIF/SPICE name = 'ECLIPJ2000') frame, is assumed to be zero.
