The data are averaged over 2 spin periods (approximately 24 seconds. The averaging intervals are overlapped and data are output on single spin period centers, the time stamp corresponding to the center of the averaging window. This results in an unevenly sampled dataset as the spin period varies. The amplitude of the ''flutter'' in the averaging window size is generally less than 0.004 seconds in the 12 second period of an orbit. Orbits that have spin period adjustment thruster firings will have larger variations in the output time steps, but such adjustments are seldom, if ever, done in the hour surrounding periapsis. Each averaging interval contains both the minimum amplitude, average amplitude and peak amplitude for that interval at each of the four frequencies. The four frequencies are 100 Hz, 730 Hz, 5.4 kHz, 30 kHz. The frequency filters are narrow-band, with a 30% bandwidth. Thus wave amplitudes are given in V/m/root(Hz). The filters are continuously active, but data are only provided at a rate determined by the spacecraft telemetry rate. The wave antenna is oriented perpendicular to the spacecraft spin axis, and so the wave instrument measures only wave fields in the spacecraft spin plane. The wave antenna is a small Y-shaped structure, with effective separation of 0.76 meters. Other datasets on the CD-ROM are the Ephemeris which contains spacecraft position in Venus Solar Orbital coordinates, spacecraft altitude, solar zenith angle, Venus centered longitude and latitude, spacecraft spin axis components, celestial longitude and latitude of the spacecraft, celestial longitude of the earth, and the Sun-spacecraft range.

CONFIDENCE_LEVEL_NOTE = " The instrument noise level (and hence sensitivity) is determined by the ambient environment at the time of observation. Photo- electrons emitted from various spacecraft surfaces appear to be a strong source of electric field interference. As a consequence data acquired when the spacecraft is in sunlight often are contaminated by spin modulated interference, especially when the spacecraft is in the low density solar wind, where the Debye length is several meters. The noise is usually lowest when the antenna elements are in the spacecraft shadow. The noise level is also reduced when the spacecraft is deep within the dayside ionosphere, where the Debye length is much smaller than the antenna size. The noise is not present when the spacecraft is within the optical shadow of the planet. In this case, however, additional noise features are observed (mainly at 100 Hz) when the spacecraft is at low altitude within the nightside ionosphere. This interference is readily discriminated in the high resolution data, where the noise is present as a sharp pulse occurring twice per spin. The averaging scheme used can be subject to temporal aliasing when the data rate is sufficiently low, such that only one or two data are obtained per 24 second interval. Since the sampling interval and spin period are not exactly synchronized, periodic noise signals, such as the interference, are aliased by the low sampling frequency. In this case the data display periodic structure, but with a period much longer than the spin period. The instrument was calibrated in air. No attempt to incorporate changes in antenna-plasma coupling due to changes in Debye length have been included in the data processing."

The data are provided in spacecraft coordinates. In one format, apoapsis B, the magnetometer can be commanded to return 3 vectors per minor frame. In most others it transmits one vector per minor frame. In one format, periapsis E, it has no words in a minor frame. At very low sampling rates at which time the sine wave due to spacecraft spin could not be resolved. The magnetometer values are despun, and averaged on board using a Walsh transform (square wave) in phase and in quadrature with the sun. The averaged despun magnetometer data could be sampled at the rate of once per spin, once every two spins or once every 4 spins. Each sample was an overlapped average of an interval twice as long as the interval sample period to avoid aliasing. Software is provided to which allows users to convert the magnetic field data from S/C coordinates to geophysical coordinates. The program PVROT will rotate the data into Venus Solar Orbital (VSO) coordinates using the magnetic filed data and the ephemeris data. Other datasets on the CD-ROM are the Ephemeris which contains spacecraft position in Venus Solar Orbital coordinates, spacecraft altitude, solar zenith angle, Venus centered longitude and latitude, spacecraft spin axis components, celestial longitude and latitude of the spacecraft, celestial longitude of the earth, and the Sun-spacecraft range. Other ancillary datasets are the: 1) phase and offset which contains the phase amplitude of sun synchronous modulation of the 4 signals (E100, E730, E5.4 and E30K), and offsets of the G sensor. 2) The engineering dataset which contains temperatures, magnetometer modes, magnetometer sample format, magnetometer spin average select, telemetry data format, telemetry bit rate, spacecraft spin period, pulse time, the difference between the Sun pulse time and the Rip pulse time, and the pulse time flag. 3) The instrument status dataset which contains amplitudes of spin ripple, differences between amplitudes, ratio of the amplitudes, phase differences between pseudosensors, average field seen by the pseudosensors, cosine amplitude, and sine amplitude."
