Voyager 2 Uranus Magnetic Field in Uranian U1 Coordinates, Resampled, Version 1.0, 1.92 s Reduced Data Record (RDR) Data

Published by PPI | National Aeronautics and Space Administration | Catalog Last Checked: October 29, 2026 at 08:31 PM | Dataset Last Updated: October 27, 2026
* Data Set Overview * ================= This Data Set includes Data from the Low Field Magnetometer (LFM) in the Solar Wind during the Uranus Encounter. The Encounter Data (1986-01-24T07:00:00 to 1986-01-25T04:00:00) have been averaged from the 60 ms Instrument Sampling Rate to a 1.92 s resampled Rate and are provided in the Uranus Longitude (U1) Coordinate System. Magnetometer Data in the Solar Wind are given in Heliographic Coordinates and are also available in a separate Data Set. The Data Set consists of the following Columns: * 1) ctime - Decimal Seconds since 1966-01-01T00:00:00.000 * 2) pdstime - ISO Standard Time Format * 3) Spacecraft Clock Value - m65536 * 4) Spacecraft Clock Value - mod60 * 5) Spacecraft Clock Value - fds_line * 6) mag_id - Magnetometer ID: 1=LFM, 2=HFM * 7) Br - Radial Component * 8) Bphi - Longitudinal Component * 9) Btheta - Colatitudinal Component * 10) Bmag - Magnitude of the averaged Magnetic Field Components * 11) avg_Bmag - Average of the Magnitude of the raw Components * 12) lambda - Magnetic Longitude, lambda=atan(Bt/Br) * 13) delta - Magnetic Latitude, delta=asin(Bn/avg_Bmag) * 14) rms_br - Br Pythagorean RMS Deviation of the Component Average * 15) rms_bt - Bt Pythagorean RMS Deviation of the Component Average * 16) rms_bn - Bn Pythagorean RMS Deviation of the Component Average * 17) npts - Number of Points in the Average * 18) Data Flag - A Character String which indicates Software or Spacecraft Hardware Intervention which reduces Confidence in the Data, Null Flags represent "good" Data The U1 Coordinate System is a Non-inertial Spherical Coordinate System that rotates with Uranus with a Period of 17.24 h. The Magnetic Field Components in the U1 Coordinate System are: * Br - Radial Magnetic Field Component, along the Uranus to Spacecraft Line, positive away from Uranus * Bphi - East Longitudinal (U1) Magnetic Field Component * Btheta - Colatitudinal (U1) Magnetic Field Component An ancillary Data File containing the derived Spacecraft Magnetic Field is provided with these Data at a 48 s Sample Rate. These Data provide Zero Level Offsets used in the Data Processing. Spacecraft Field Data is provided in Spacecraft Coordinates. +--------------------------------------------------------+ | Parameter Characteristics | Value | ---------------------------------------------------------- | Sampling Parameter Name | TIME | | Sampling Parameter Resolution | 1.920000 | | Minimum Sampling Parameter | 19770820120000.000000 | | Maximum Sampling Parameter | UNK | | Sampling Parameter Interval | 1.920000 | | Minimum Available Sampling Int | 0.060000 | | Sampling Parameter Unit | SECOND | | Data Set Parameter Name | MAGNETIC FIELD VECTOR | | Noise Level | 0.006000 | | Data Set Parameter Unit | NANOTESLA | +--------------------------------------------------------+
