... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

Operations in Point operations use the pointer to query sets about points, delete points in a set, and move points. In all cases where interaction is required, pressing the right mouse button with the pointer in the drawing area cancels the operation. ... Report on a point in a set . ... Press the left mouse button. ... Press Delete point with the left mouse button to activate. ... Move the pointer to the new location and press the left mouse button again to register the point's new location. ...

Next: PN3DB and NOPN3DB Up: Details of SCHED Parameters Previous: PLOT Contents . POINT is used to tell SCHED to convert this scan to a reference pointing scan. If the argument is zero (which is the value it will get if POINT is specified without an argument), all stations that are in any group and have appropriate frequencies as specified in the PEAKFILE (see also PEAKINIT ) will be used. ... POINT=-1 means don't add a pointing scan even if you can. ... None means zero. ... Example: POINT=2 . ...

SINGULAR POINTS IN THE SOLAR CHROMOSPHERE . ... In the structure of the solar chromosphere, containing information on the configuration of the magnetic field, we have found and identified all the main types of the singular points ( see Fig. 1 ), which are known as inherent features of the 2-D vector field. ... The main types of the singular points are the node, the focus, the center, and the saddle. ... Singular point of the focus type in the solar chromosphere. ...

... Ignacio Ugarte Urra's PhD thesis topic is the investigation of coronal bright points. In his first paper (in collaboration with Gerry Doyle and Maria Madjarska) he investigated the formation, evolution and decay of a coronal bright point via a spectroscopic analysis of its transition region counterpart and the evolution of the underlying magnetic bipole during 3 days of almost continuous observations. ... In general the bright point has a radiance 4 times higher than that of the network. ...

XPA access points are composed of two parts: a general class and a specific name. ... When clients communicate with XPA access points, they specify which access points to communicate with using an identifier of the form: class:name All registered XPA access points that match the specified identifier will be available for communication (subject to access control rules, etc.) ... These socket identifiers are displayed as the fourth argument in the xpans display of registered access points. ...
