Voyager 2 Uranus Magnetic Field in Uranian U1 Coordinates, Resampled, Version 1.0, 9.6 s Reduced Data Record (RDR) Data

* Data Set Overview\n* =================\n\nThis 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 1.92 s averaged Data to a 9.6 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.\n\nThe Data Set consists of the following Columns:\n\n* 1) ctime - Decimal Seconds since 1966-01-01T00:00:00.000\n* 2) pdstime - ISO Standard Time Format\n* 3) Spacecraft Clock Value - m65536\n* 4) Spacecraft Clock Value - mod60\n* 5) Spacecraft Clock Value - fds_line\n* 6) mag_id - Magnetometer ID: 1=LFM, 2=HFM\n* 7) Br - Radial Component\n* 8) Bphi - Longitudinal Component\n* 9) Btheta - Colatitudinal Component\n* 10) Bmag - Magnitude of the averaged Magnetic Field Components\n* 11) avg_Bmag - Average of the Magnitude of the raw Components\n* 12) lambda - Magnetic Longitude, lambda=atan(Bt/Br)\n* 13) delta - Magnetic Latitude, delta=asin(Bn/avg_Bmag)\n* 14) rms_br - Br Pythagorean RMS Deviation of the Component Average\n* 15) rms_bt - Bt Pythagorean RMS Deviation of the Component Average\n* 16) rms_bn - Bn Pythagorean RMS Deviation of the Component Average\n* 17) npts - Number of Points in the Average\n* 18) Data Flag - A Character String which indicates Software or Spacecraft Hardware Intervention which reduces Confidence in the Data, Null Flags represent "good" Data\n\nThe 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:\n\n* Br - Radial Magnetic Field Component, along the Uranus to Spacecraft Line, positive away from Uranus\n* Bphi - East Longitudinal (U1) Magnetic Field Component\n* Btheta - Colatitudinal (U1) Magnetic Field Component\n\nAn 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.\n\n+--------------------------------------------------------+\n| Parameter Characteristics      | Value                 |\n----------------------------------------------------------\n| Sampling Parameter Name        | TIME                  |\n| Sampling Parameter Resolution  | 9.6                   |\n| Minimum Sampling Parameter     | 19770820120000.000000 |\n| Maximum Sampling Parameter     | UNK                   |\n| Sampling Parameter Interval    | 9.6                   |\n| Minimum Available Sampling Int | 0.060000              |\n| Sampling Parameter Unit        | SECOND                |\n| Data Set Parameter Name        | MAGNETIC FIELD VECTOR |\n| Noise Level                    | 0.006000              |\n| Data Set Parameter Unit        | NANOTESLA             |\n+--------------------------------------------------------+
