        "Description": "Hourly averaged definitive multispacecraft interplanetary parameters dataThe Heliographic Inertial (HGI) coordinates are Sun-centered and inertially fixed with respect to an X-axis directed along the intersection line of the ecliptic and solar equatorial  planes. The solar equator plane is inclined at 7.25 degrees from the ecliptic. This direction was towards ecliptic longitude of 74.367 degrees on 1 January 1900 at 1200 UT; because of precession of the celestial equator, this longitude increases by 1.4 degrees/century. The Z axis  is  directed perpendicular and northward from the solar equator, and the Y-axis completes the right-handed set. This system differs from the usual heliographic coordinates (e.g. Carrington longitudes) which are fixed in the frame of the rotating Sun.The RTN system is fixed at a spacecraft (or the planet). The R axis is directed radially away from the Sun, the T axis is the cross product of the solar rotation axis and the R axis, and the N axis is the cross product of the R and T axes.  At zero heliographic latitude, when the spacecraft is in the solar equatorial plane, the N and solar rotation axes are parallel.Latitude and longitude angles of solar wind plasma flow are generally measured  from the radius vector away from the Sun. In all cases, latitude angles are positive for north-going flow.  The flow longitude angles have been treated differently for the near-Earth data, i.e. the OMNI, and for the deep space data. The flow is positive for the  near-Earth data when coming from the right side of the Sun as viewed  from  the Earth, i.e. flowing toward +Y from -X GSE or opposite to the direction of planetary motion. On the other hand, the flow longitudes for the deep space spacecraft use the opposite sign convection, i.e. positive for flow in the +T direction in the RTN system.",
