Description

STEREO Ahead reprocessed IMPACT/MAG Beacon magnetic field vector component and vector magnitude data expressed in Heliographic, HG, Radial-Tangential-Normal, RTN, Cartesian coordinates around the 2015 solar conjunction. * Version 1: Used internally at UCB and UCLA ONLY, No corrections applied to raw MAG data * Version 2: Offset correction applied to MAG data * Version 3: Initial algorithm for correcting glitches for the X sensor on STEREO Ahead applied * Version 4: Improvement in glitch correction algorithm applied * Version 5: Further refinement of the glitch correction for the X sensor on STEREO Ahead, Also, two timing issues resolved: - a) applying a 6 ms time shift to account for time lag between IMPACT IDPU and MAG - b) fixing an occasional 1 s 'glitch' * Version 6: Added FILTER_VALUE variable
