The solar rotation axis is the primary vector: the Z axis points in the solar north direction. The solar ascending node on the ecliptic of J2000 forms the X axis. The Y axis is Z cross X, completing the right-handed reference frame. HEE : Heliocentric Earth Ecliptic Frame - All vectors are geometric: no aberration corrections are used. The position of the Earth relative to the Sun is the primary vector: the X axis points from the Sun to the Earth. The northern surface normal to the mean ecliptic of date is the secondary vector: the Z axis is the component of this vector orthogonal to the X axis. The Y axis is Z cross X, completing the right-handed reference frame. HEEQ : Heliocentric Earth Equatorial Frame - All vectors are geometric: no aberration corrections are used. The solar rotation axis is the primary vector: the Z axis points in the solar north direction. The position of the Sun relative to the Earth is the secondary vector: the X axis is the component of this position vector orthogonal to the Z axis. The Y axis is Z cross X, completing the right-handed reference frame. spase://SMWG/Person/Elena.Budnik MetadataContact spase://SMWG/Repository/CDPP/AMDA Online Open http://amda.cdpp.eu NetCDF PSA spase://CDPP/Instrument/AMDA/Rosetta/Ephemeris Ephemeris 2004-03-03T00:00:00Z 2014-08-04T00:00:00Z PT1H xyz_hee ros_xyz_hee AU 3 x 0 ros_xyz_hee(0) y 1 ros_xyz_hee(1) z 2 ros_xyz_hee(2) Positional xyz_heeq ros_xyz_heeq pos.bodyrc;instr.obsty km Cartesian HEEQ TimeSeries 3 x 0 ros_xyz_heeq(0) y 1 ros_xyz_heeq(1) z 2 ros_xyz_heeq(2) Positional xyz_hci ros_xyz_hci pos.bodyrc;instr.obsty km Cartesian HCI TimeSeries 3 x 0 ros_xyz_hci(0) y 1 ros_xyz_hci(1) z 2 ros_xyz_hci(2) Positional distance ros-sun r_sun_ros AU TimeSeries
