... Table data are arranged in columns and rows, and stored in MIDAS files with the extension .tbl . ... An item in a table is accessed by giving its column and row in addition to the table name. The row number can either be given as an absolute value (i.e. the sequence number) or indicated by the value in a previously defined reference column. ... A table can be always expanded in the sense that its number of columns and rows is automatically increased when the allocated space is exceeded. ...

Giant radio galaxies constitute a class of radio sources with linear sizes on the megaparsec scale (Saripalli 1988). ... The Westerbork Northern Sky Survey (WENSS) has discovered several cases of "inner-double" or "double-double" giant radio galaxies: the findings suggest that such structures predominantly occur among the larger of radio galaxies. ... Close to the core of B0114-476, a narrow jet-like feature is seen directed toward the southern inner lobe which also has the brighter hotspots. ...

The silicates that produce the 10 and 18 micron features appear to be broadly similar to terrestrial minerals such as Forsterite and Enstatite. ... Where pre-solar silicate dust grains can be isolated from meteorite material, these also tend to be Mg-rich silicates rather than Fe-rich silicates. ... It has been suggested that the interstellar silicate grains have a different 10 micron feature profile than what is observed for the silicates around evolved stars. ...

spaceweb@oulu.fi - last update: 20 September 1998, 2020 UT (RR) . Traveling Convection Vortex (TCV) is a name given to a specific type of daytime magnetic impulsive events observed by high-latitude ground-based magnetometer arrays. Since the most likely source for TCVs is the solar wind , they are considered to be important processes in transfering energy from the solar wind into the magnetosphere . ... For example, one AMPTE Lithium release in the solar wind caused a TCV event . ...

... A detailed study of two consecutive bright points observed simultaneously with CDS, EIT and MDI is presented. The analysis of the evolution of the photospheric magnetic features and their coronal counterpart shows that there is a linear dependence between the EIT Fe XII 195? flux and the total magnetic flux of the photospheric bipolarity. ... In a follow-up study, we used wide slit (90arcsec240arcsec) movies of four EIT coronal bright points (BPs) obtained with CDS. ...
