Ulysses Solar Wind Observations Over the Poles of the Sun (SWOOPS) Alpha Particle Distribution Function Hot Plasma Moments, Level H1, 4 min Data
ReleaseDate

Description
This File contains the Moments obtained from the Distribution Function of Alpha Particles after Deconvolution using the same Magnetic Field Values used to construct the Matrices. The Vector Magnetic Field and the Particle Velocity are given in Inertial RTN Coordinates. The Magnetic Field was obtained for the Time at which the Peak of the Alpha Particle Distribution Function was measured. The Particle Velocity was obtained after rotating the Fluid Velocity from Spacecraft to RTN Coordinates and taking into account the Spacecraft Velocity. During Periods of Spacecraft Nutation only the Bulk Speed and Density are reliable, individual Velocity Components and Temperatures are invalid. The Beginning of scientifically useful SWOOPS Data is at Day 322, 00:59 of 1990; at that Time the Spacecraft was already nutating; Nutation ceased as of Day 351, 22:00, 1990. There are small systematic Uncertainties in the Velocity Components. These are due to such Effects as Uncertainty in the Accuracy of Alignment on the Spacecraft, relatively wide Angular Bins, Variation in Gains between Channeltrons, etc. The Velocity Component Data should not be used for Studies of large scale, long term, Solar Wind Deflection. The Data are generally suitable for all other Studies.
