comment

RTN coordinates consist of R (radial component, Sun to the spacecraft), T (tangential component, parallel to the Solar Equatorial plane and perpendicular to R), and N (normal component, completes right handed set). These MAG data were processed (calibrated, and rotated into RTN coordinates) by the Cassini MAG team at Imperial College. They were acquired by the PDS PPI node at UCLA where they were converted from binary to ASCII, and the B-field magnitude, and position data removed. These data have been processed using an updated calibration that was produced using the Proximal Orbit data. Note that some of the data files from this collection contained timing errors. This file, however, contains no identified timing errors. For more information on the timing errors, and on this and previous versions of the data, please refer to the collection description document (data-full-rtn-desc.txt). These spice kernels were used to process these data but are not archived: 02143_02153ra.bc 171215R_SCPSEops_97288_17258.bsp
