Stop: Instrument:IMP 8 Magnetic Field Experiment Resource:Catalog
A complete list of bow shock crossings observed by IMP 8 spacecraft. The shock crossings were manually identified in magnetic field and/or thermal plasma measurements by J. Merka, A. Szabo, K. Paularena, J. Richardson, and T. Narock. Each identified crossing was reviewed by at least two persons from the team. Upstream parameters are as measured by IMP 8 on the solar wind side of the shock, typically over a few-minute interval judged by the IMP field and plasma teams as stable. For multiple-shock records, all upstream parameters are for the first shock crossing. Downstream parameters are as measured by IMP 8 on the magnetosheath side of the shock, typically over a few-minute interval. For a multiple-shock records, all downstream parameters are for the first shock crossing if possible.

Stop:2004-12-31 01:00:00 Instrument:Triaxial Fluxgate Magnetometer (MAG) Resource:NumericalData
Data Set Overview ================= This data set contains hour averages of the interplanetary magnetic field (IMF) measurements obtained by the triaxial fluxgate magnetometer experiment on Voyager 1. Identical instruments on Voyager 1 and 2 were designed to measure the IMF between Earth and Saturn (10 AU) during the primary Voyager mission. The design and performance yielded absolute accuracies to better than < 0.1 nT. In general, each component of the hourly average has an uncertainty of up to (+/- 0.05 nT) in the region beyond 10 AU. More accurate measurements can be obtained by special processing of the data, but it was not feasible to do this for the entire data set included here. The magnetic field magnitude in nT is provided along with angles of the field vector in the spacecraft- centered Heliographic (HG) coordinate system, also known as RTN. Coordinate System ================= Interplanetary magnetic field studies make use of two important coordinate systems, the Inertial Heliographic (IHG) coordinate system and the Heliographic (HG) coordinate system. The IHG coordinate system is use to define the spacecraft's position. The IHG system is defined with its origin at the Sun. There are three orthogonal axes, X(IHG), Y(IHG), and Z(IHG). The Z(IHG) axis points northward along the Sun's spin axis. The X(IHG) - Y(IHG) plane lays in the solar equatorial plane. The intersection of the solar equatorial plane with the ecliptic plane defines a line, the longitude of the ascending node, which is taken to be the X(IHG) axis. The X(IHG) axis drifts slowly with time, approximately one degree per 72 years. Magnetic field orientation is defined in relation to the spacecraft. Drawing a line from the Sun's center (IHG origin) to the spacecraft defines the X axis of the HG coordinate system. The HG coordinate system is defined with its origin centered at the spacecraft. Three orthogonal axes are defined, X(HG), Y(HG), and Z(HG). The X(HG) axis points radially away from the Sun and the Y(HG) axis is parallel to the solar equatorial plane and therefore parallel to the X(IHG)-Y(IHG) plane too.

Data Set Overview ================= This dataset contains Voyager 1 magnetometer data from the interplanetary cruise averaged to 48 second samples in Heliographic coordinates. Data Processing =============== The high resolution data submitted to the NSSDC has its origins in the original MVS 'Summary' data sets formally produced on the NSSC IBM MVS mainframe system. The original data sets contain a mix of engineering, electron, magnetic field and plasma data. The Voyager magnetometer (MAG) experiment now resides on a dedicated workstation where only MAG data are processed. All Voyager MAG data submitted to the NSSDC consists wholly of high resolution LFM averages. These files consist of a set of averages applied across all of the mission's differing telemetry modes. In the case of the Magnetometer Experiment, the records contain both 1.92 second, 9.6 second and 48 second averages. 1.92 second averages are created from the detail detail data, 9.6 second averages are created from 1.92 second averages and 48 second averages are created from the 9.6 second averages. All data in this NSSDC data set are interplanetary and in heliographic coordinates (see below). An ASCII formated data set containing key components of the 48 second magnetic field data and ephemeris data has been created allowing more convenient access to high resolution Voyager magnetometer data. Coordinate System ================= Interplanetary magnetic field studies make use of two important coordinate systems, the Inertial Heliographic (IHG) coordinate system and the Heliographic (HG) coordinate system. The IHG coordinate system is use to define the spacecraft's position. The IHG system is defined with its origin at the Sun. There are three orthogonal axes, X(IHG), Y(IHG), and Z(IHG). The Z(IHG) axis points northward along the Sun's spin axis. The X(IHG) - Y(IHG) plane lays in the solar equatorial plane. The intersection of the solar equatorial plane with the ecliptic plane defines a line, the longitude of the ascending node, which is taken to be the X(IHG) axis. The X(IHG) axis drifts slowly with time, approximately one degree per 72 years. Magnetic field orientation is defined in relation to the spacecraft. Drawing a line from the Sun's center (IHG origin) to the spacecraft defines the X axis of the HG coordinate system. The HG coordinate system is defined with its origin centered at the spacecraft. Three orthogonal axes are defined, X(HG), Y(HG), and Z(HG). The X(HG) axis points radially away from the Sun and the Y(HG) axis is parallel to the solar equatorial plane and therefore parallel to the X(IHG)-Y(IHG) plane too. The Z(HG) axis is chosen to complete the orthonormal triad. An excellent reference guide with diagrams explaining the IHG and HG systems may be found in Space and Science Reviews, Volume 39 (1984), pages 255-316, MHD Processes in the Outer Heliosphere, L. F.

Version 1.1 ----------- This version 1.1 data set replaces the version 1.0 data set (DATA_SET_ID = VG1-J-MAG-4-1.92SEC) previously archived with PDS. Changes to this version include the addition of data columns not included in version 1.0, the modification of time format and flag values, and upgrade of associated labels and catalog templates to PDS version 3.2. Data Set Overview ================= This data set includes calibrated magnetic field data acquired by the Voyager 1 Low Field Magnetometer (LFM) during the Jupiter encounter. Coverage begins in the solar wind inbound to Jupiter and continues past the last outbound bowshock crossing. The data are in System III (1965) (SYS3) coordinates and have been averaged from the 60 ms instrument sample rate to a 1.92 second sample rate. All magnetic field measurements are given in nanoTesla (nT). The magnetic field data are calibrated (see the calibration description included in the Voyager 1 Magnetometer instrument catalog file for details). Parameters ========== The full LFM instrument sample rate is 1 sample per 0.06 seconds. Full telemetry resolution 'detail' data must be obtained from the instrument team. These data have been resampled at 1.92 seconds from the detail data. The LFM has eight dynamic ranges. The instrument is designed switch between dynamic ranges automatically depending upon the observed magnetic field magnitude and fluctuations. Instrument digitization uncertainty depends upon dynamic range as indicated in the following table (from [BEHANNONETAL1977]). ----------------------------------------------- LFM Dynamic ranges and quantization uncertainty ----------------------------------------------- Range (nT) Quantization (nT) ----------------------------------------------- 1. +/- 8.8 +/- .0022 2. +/- 26 +/- .0063 3. +/- 79 +/- .019 4. +/- 240 +/- .059 5. +/- 710 +/- .173 6. +/- 2100 +/- .513 7. +/- 6400 +/- 1.56 8. +/- 50,000 +/- 12.2 Processing ========== Voyager EDR's undergo the following processing in order to produce these 1.92 second averaged summary data: * Read EDR * Unpack header block (rec. id, s/c id, tel. mode, FDS counts, data flags) * Convert selected time tags to integer time (yy/ddd/hh:mm:ss.fff) * Unpack sub-header block (MAG status words, plasma data) * Unpack science block (MAG counts) * Convert counts to gammas * Apply sensor and boom alignment matrices * Rotate (optional) 1.92 second averages while averaging detail gammas to create 1.92 second averages * Write Summary record Counts are measured onboard using 12 bit words that may represent values ranging from 0-4096. Integer counts are converted to magnetic field units (gammas) by subtracting a zero offset, from the measured MAG value and multiplying this difference by the sensitivity of the instrument.

The magnetic field data are calibrated (see the calibration description included in the Voyager 1 Magnetometer instrument catalog file for details). Ephemeris data, provided in 96 second sampled System III (1965) coordinates, have been merged into the data files for this data set. The ephemeris data, generated from Voyager 1 SEDR and provided by the Voyager MAG Team, are part of the data set VG1-J-POS-6-SUMM-S3COORDS-V1.1.
