The records also hold flow velocity vector components and direction angles in HERTN and RTN coordinates. Chi-squared and statistical uncertainties are included, as are various flags. STEREO position information is given in radial distance and HEE, HEEQ and HCI direction angles. Please acknowledge STEREO PLASTIC Investigation (A.B.
