VG1 JUP MAG RESAMPLED HELIOGRAPHIC (RTN) COORDS 48.0SEC V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: August 03, 2025 | Last Modified: 2025-07-17
This data set includes data from the Low Field Magnetometer (LFM) during the inbound Jupiter encounter beginning in the solar wind and continuing until at least the first magnetopause crossing. The magnetometer are given in Heliographic coordinates and the data have been averaged from the 60 ms instrument sample rate to a 48 second resampled rate. The data set consists of the following columns: 1) UT of the sample in the format yyyy-mm-ddThh:mm:ss.sssZ, 2) continuous time (decimal seconds since 1966-01-01T00:00:00.000), 3-5) spacecraft clock (m65536, mod60, fds-line), 6) magnetometer id (1 = LFM, 2 = HFM), 7) Br (radial, Sun to spacecraft, B-field component), 8) Bt (azimuthal B-field component, positive in the direction of planetary orbital motion), 9) Bn (North/South B-field component, positive northward), 10) Bmag (magnitude of the averaged components), 11) avg_Bmag (average of the magnetic field magnitudes), 12) delta (latitude = arcsin(Bn/Bmag)), 13) lambda (longitude = 180. - atan(Bt/Br)), 14-16) rms vector, 17) npts (number of points in average), 18) data flag. - a flag value that indicates either software error or spacecraft hardware interference reduced confidence in this record (flag value of 1 is bad , 0 is good or unchecked). All magnetic field observations are measured in nanoTesla. All of the magnetic field data are calibrated (see the instrument calibration description for more details). The reference documents for this data set are: [NESSETAL1979], [LEPPINGETAL1981], [CONNERNEYETAL1981], [BEHANNONETAL1981].
