Next: A Universal Diagram for Up: ``Ecology'' of Magnetic Rotators Previous: The Corotation Radius . The interaction of a magnetic rotator with the surrounding plasma to a large extent depends on the relation between the four characteristic radii: the stopping radius, , the gravitational capture radius, ? , the light cylinder radius, ? , and the corotation radius, ? . ... Hence, the classification of the interaction regimes may well mean the classification of magnetic rotators. ...

Additionally, as mentioned above, invert does not attempt to completely correct for the primary beam attenuation where there is too little data (i.e. some primary beam attenuation is in the output image). ...

... Magnetic fields, subatomic particles, etc., traveling in different directions fill the universe. Do they deflect or otherwise affect one another? If so, isnт??t the information we get from them distorted? ... Neutrino astronomy, which is still in its infancy, is attractive because neutrinos interact so weakly with matter that few of these distorting effects occur.

... The magnetic field of the Earth has been investigated by satellites for several decades now, and enough of it is known to model its average strength and shape during different levels of overall magnetic activity. Presently the most used empirical global magnetic field models are the Tsyganenko models (1987, 1989) , referred to as T87 and T89, respectively, although even these consist of several submodels. ...

A crucial aspect of 3D Monte Carlo radiative transfer is the choice of the spatial grid used to partition the dusty medium. We critically investigate the use of octree grids in Monte Carlo dust radiative transfer, with two different octree construction algorithms (regular and barycentric subdivision) and three different octree traversal algorithms (top-down, neighbour list, and the bookkeeping method). ... The total number of grid cells, however, depends on the geometry of the model. ...

... Two files from two exposures (even from different observations or instruments) are taken as input. These may be EPIC event lists or two other additional files (attitude files, orbit files etc [see comments]). ... Warnings are given when the event files are deemed not entirely compatible (i.e. their INSTRUME or FILTER keywords are different). ... Given here is a summary of the current conditions whereby event files (or parts thereof [blocks/columns etc]) are or are not merged. ...
