... Several analysis strategies for computation of systematic part in the radio source velocities can be used: a) estimate source position and velocities from global solution, then fit spherical harmonics to the velocities (Gwinn et al. 1997); b) compute the coefficients of spherical harmonics as global parameters (MacMillan 2005; Titov 2008); c) compute velocities from position time series, then fit spherical harmonics to the velocities. ... Time series statistics is shown in Table 1. ...

... The low energy plasma composition spectrometer AMEI-2 is built to be able to find in the low energy range of the phase space (E, q, j) and separate the fluxes of the major ion species in the magnetotail - H+, He++, He+ and O+, and analyse their energy and angular distributions. ... Electrostatic angular scanning in one direction and the use of the spin of the satellite to sample the other angle give the ability to measure 2-D distributions for each ion specie several times per spin. ...

Next: Initial conditions Up: Old neutron star distribution Previous: Introduction . The problem to be solved is to find stationary space distribution of stars which have had certain initial space and velocity distributions and move in a given potential. ... In principle, the most straightforward way to obtain the solution is to integrate directly the equations of motion for a sufficiently large number of stars with different initial conditions. ... Then space density is given by . ...
