Data Set

This data set contains high time resolution magnetic field vectors acquired by the Galileo magnetometer (MAG). It includes both satellite flyby and non-flyby data. These data were acquired in order to characterize various portions of the Jovian magnetosphere at high time resolution. The Galileo Magnetospheres Working Group (MWG) collectively acquired high time resolution data for short intervals in order to try and regain some of the magnetospheric science lost due to the low data rates of the phase 2 mission (no high gain antenna) mission. These observations are scattered in Jovian distance, local time, System III longitude, etc. in order to provide some insight into processes that may be active in different regions of the magnetosphere. There were a few orbits in which MAG obtained high-resolution coverage in conjunction with remote sensing (typically NIMS) observations. Regular MWG high-resolution observations were recorded to tape using the 7.68 bits/second Low-Rate Science and Plasma Wave (LPW) tape mode. Observations using higher tape speed modes included recorded LPW rate data as well. In cases where the coverage provided was adequate, and when there was sufficient bits-to-ground (BTG) allocation to return them, these 'ridealong' observations provided coverage in addition to the regular MWG observations. A list of ridealong recordings is provided in the 'Data Coverage and Quality' section of this document. Satellite Flybys: One of the primary objectives of the Galileo mission was to characterize the magnetic signatures of Jupiter's Galilean satellites, determine their sources, and study their interactions with the Jovian system. In particular, confirming the presence of a sub-surface ocean on Europa became a major focus of the Europa Mission (GEM). The Millennium Mission (GMM) also included a flyby of Amalthea. Inner Magnetosphere: Characterizing the Io torus was a high priority goal of the MWG throughout the mission. In order to protect the spacecraft and instrument from the high radiation of the inner magnetosphere, most of the inner magnetosphere observations were deferred until late in GEM and GMM. Middle Magnetosphere: In the middle magnetosphere, a variety of observations were made in order to characterize the distribution of plasma in the plasma sheet and to examine the regions where field lines likely map to the auroral oval. Magnetotail: Another of the MWG high priority science objectives was to study the structure of the Jovian magnetotail. Orbit C09 was specifically designed to meet this objective. Apojove was near 150 Rj at local midnight. High time resolution data was acquired for five intervals at various distances and local times. Table 1. gives information on the coverage provided by the various MAG high time resolution observations. In addition to start time and duration, the table describes the minimum and maximum distance from the spacecraft to Jupiter, and the local hour and Sys. 3 west longitude (WLON) of the spacecraft at the beginning and end of the recorded interval. Local hour is given in terms of decimal hours (0.0-23.9). WLON is in units of degrees (0-359

Processing

The processing of MAG data is performed as a series of operations on the data. 1) Extract raw MAG and Attitude and Articulation and Control System (AACS) data from the packetized telemetry files. Set sample time tags, sort data on time, and remove duplicate samples. 2) Remove the calibration estimate applied by the instrument. This involves multiplying the data by the inverse of the onboard geometry matrix, dividing by gain factors, and adding offsets to the data. This returns the data to sensor coordinates. 3) Apply post orbit inflight calibration (scale to nT, subtract offsets, multiply by coupling matrix). This properly orients the data in the spinning spacecraft reference frame. 4) Merge in the AACS data, interpolate to MAG sample times, correct the phase angle for phase delays in the instrument and despin the data into IRC coordinates. 5) Transform data into geophysical coordinates using SPICE based software and SPICE kernels.

Parameters

Data Sampling The magnetometer samples the field thirty times per second. These data are recursively filtered and decimated down to a sample rate of two vectors per minor frame (mf = 2/3 second) before being recorded to tape in LPW format. For all orbits except G01 and G02, the MAG data are evenly sampled in time, 3 samples per second. Due to an instrument programming error that occurred during the instrument reprogramming for phase 2 operations, the G01 and G02 LPW data are unevenly sampled in time within the minor frames. Each minor frame consists of 10 real-time interrupts (RTI). In the G01 and G02 data, the mid minor frame sample occurs half an RTI later than it should. This problem was corrected before the C03 orbit. All data are time stamped with universal time (UT) at the spacecraft when the instrument sampled data within the recursive filter. MAG uses fixed gains to acquire data [KIVELSONETAL1992]. Gain states must be manually changed by sending a gain change command to the instrument. There are 3 ranges of field strengths that the instrument can measure:

Table 3. Magnetometer Ranges ---------------------------------------------------------------Field Range (nT) Magnetometer, field range min max ---------------------------------------------------------------1/64 - 32 Outboard low field 1/4 - 512 Outboard high field, Inboard low field 8 - 16384 Inboard high field Recursive filtering of LPW data makes the apparent digitization step size much smaller than it appears in Table 3. Variation in the vector field components attributable to the spacecraft spin reduces the effective digitization levels in the filtered data to about one quarter of the A/D step size. The outboard magnetometer, low field mode was used to acquire data beyond 60 Rj and the inboard magnetometer, high field mode was used to acquire data inside of 9 Rj. During the prime mission, the both the inboard low field and the outboard high field modes were used to acquire data between 9-60 Rj. As the outboard magnetometer is further out from the main body of the spacecraft on the boom than the inboard magnetometer it is impacted less by spacecraft fields. For this reason it was initially preferred over the inboard magnetometer. However, the outboard magnetometer began to experience abrupt changes in the sensor zero levels towards the end of the prime mission. As a result, the inboard magnetometer, low field mode was used to acquire data between 9-60 Rj throughout the remainder of the mission.

Data

The data are provided in four (4) coordinate systems (IRC, System III, satellite centered 'planetographic', and Phi-Omega). For moon flybys, data are provided all four of these coordinate systems. For non-flyby observations only IRC and System III coordinates are provided. Data from each coordinate system are stored in separate files with simple ASCII table formats. The structure and contents of the data files are described below. The coordinate systems are described later in this document in the section entitled 'Coordinate Systems.'

All of the SPICE kernels used to produce this data set are contained on the MWG archive volume DVD in the EXTRAS/SPICE/KERNELS directory. The kernels (PDS PRODUCT_ID) used to create this were: S980326B.TSP - Prime Mission Reconstruction (JA - E12) S000131A.TSP - GEM reconstruction (E12-E26) S030129A.TSP - GMM (I27-A34) reconstruction, J35 predict PCK00007.TPC - Planetary constants kernel (2000-04-24) MK00062B.TSC - Galileo spacecraft clock kernel

Ancillary Data

There are several files that are provided in addition to the data files themselves that may be of value to the user. These include a table of important spacecraft and instrument events including onboard calibration parameters, an instrument calibration table, a description of instrument anomalies and resolutions, and a set of quick-look or 'browse' plots of the data. Due to bit rate limitations some of the targetted satellite flybys had no high-resolution recordings associated with them. For these and a few distant flybys data are provided in satellite-centered coordinates at the RTS data rate. Included are Europa flybys in E19 and I25, Ganymede flybys in C9 and E12, and Callisto flybys in C21, C22, and C23. The C20 Callisto flyby was lost due to a telemetry outage. While these data are part of Survey Data Set, they are ancillary to this data set.

Coordinate Systems

The data are provided in four coordinate systems. Data are provided in the spacecraft coordinate system in order to aid in the interpretation of particle instrument data. The other three coordinate systems provided for use in Jovian magnetospheric studies. Inertial Rotor Coordinates (IRC)

The IRC coordinate system takes the basic rotor coordinate system (Y along the boom, Z opposite the high gain antenna) which is spinning, and despins it using the rotor spin angle. For this reason IRC coordinates are sometimes referred to as 'despun spacecraft coordinates.' In this system, Z still points along the spin axis opposite the HGA (or roughly anti-Earthward), X is approximately parallel to the downward ecliptic normal, and Y completes the right-handed set (pointing roughly towards dawn). System III [1965] Coordinates (SYS3)

System III [1965] (SYS3) magnetic field vector components form the standard right-handed spherical triad (R, Theta, Phi) for a Jupiter centered system. Namely, R is radial (along the line from the center of Jupiter to the center of the spacecraft), and positive away from Jupiter. Phi, the azimuthal component, is parallel to the Jovigraphic equator (Omega x R) and positive in the direction of corotation. Theta, the 'southward' component, completes the right-handed set. For SYS3 trajectory both east and west longitudes are provided. West longitudes are related to east longitudes by to the algorithm: west longitude = 360. - east longitude <degrees> West longitude is defined such that it appears to increase with time for a stationary observer [DESSLER1983]. Note, however, that R, latitude, and west longitude constitute a left handed set. The SYS3 1965 prime meridian is the sub-Earth longitude of 1965-01-01 00:00 UT. The spin rate (which was determined from the rotation rate of the magnetic field) is 9 hrs 55 min 29.719 sec. (See [DESSLER1983] for a discussion on Jovian longitude). R is the radial (Jupiter's center to spacecraft center) distance. Latitude is planetocentric. Satellite-Centered Planetographic (Right Handed) Coordinates (SPRH)

SPRH is a spherical 'planetocentric' coordinate system, centered at the satellite. The magnetic field components are the standard right-handed spherical triad: R, Theta, and Phi. R is radial (along the line from the center of the satellite to the center of the spacecraft), and positive away from the satellite. Phi, the azimuthal component, is parallel to the satellite's planetographic equator (Omega x R) and positive in a right-handed sense. Theta, the 'southward' component, completes the right-handed set. Trajectory components are also right-handed. Since all of the satellites studied are nearly phase locked to Jupiter, the SPRH prime meridian is effectively the sub-Jupiter meridian. More precise definitions are provided by the IAU [1994] (see Table 4). Longitude is measured from the prime meridian and is positive in a right-handed sense (see figure below). R is the radial distance (satellite's center to spacecraft center). Latitude is planetocentric.

The PhiO (Satellite Phi=X, Omega=Z) fixed coordinate system is defined by using the two vectors Phi, the corotation velocity vector at the satellite, and Omega, the Jovian spin axis. Phi is positive in the direction of corotation and Omega is positive northward. Y completes the right-handed set (pointing towards Jupiter). The basis vectors of the coordinate system are fixed at the epoch time (satellite closest approach, see Table 2). The spacecraft trajectory information takes the instantaneous range vector (R) from the satellite center to the spacecraft and resolves it into XYZ components. Ranges are given in units of satellite radii (see Table 4).
