... This task takes an OM OSW source list and a source number and produces EVSELECT region files for the source and its associated background. The source extraction region is a circle, centred on the source position and extending out to srcrad (default 3) times the FWHM of the source PSF (as given in the source list). ... If a source is within srcrad FWHM of the background extraction annulus then a circle of srcrad FWHM surrounding this source is excluded from the background region. ...

... The task uvsector flags a set of visibilities based on their u-v position angle. ... If there is a glitch an a particular time, the bad data will cause a stripe pattern in the resultant image which is at right angles to the spoke. The position angle of the stripe can be used to determine the u-v plane position angle of the glitch. ... Task uvsector will flag a sector of visibility data with a given u-v position angle (or hour angle). ... You do this by specifying a long, thin region in a image. ...

... While "First Light" was achieved at the second 8.2-m VLT Unit Telescope (UT2) ahead of schedule, UT1 produced its sharpest image so far. ... It had long been ESO's intention to provide "real" names to the four VLT Unit Telescopes, to replace the current, somewhat dry and technical designations as UT1 to UT4. ... The participants were left with the impression of mounting expectations, just four weeks before the first VLT Unit Telescope, Antu (UT1), will receive the first visiting astronomers. ...

... Sunspot Region 30 . ... The solar active region designated number 0030 is now appearing on the visible hemisphere of the closest star. Dwarfed by the Sun's disk, the group of sunspots which make up region 30 actually cover an enormous area -- nearly 10 times the size of Earth. ... The star cluster in RCW38 was hiding. ... The reason is that the open cluster is so young that it is still shrouded in thick dust that absorbs visible light. ... Proxima Centauri: The Closest Star . ...

. On the plot the days are shown along X axis and Universal time along Y axis. The regions in the first satellite positions are shown by the regions symbols and colour. The time intervals of the conjugation between considered couple of the satellites during day are shown as a 'wide boxes'. The corresponding numerical file contains the coordinates of both satellites during magnetic conjugations. Dr. Victoria Prokhorenko . Modified 17 June 1999

Dense regions reach a maximum size and then fall back into a bound object like a cluster of galaxies. Once the cluster is formed, its physical size remains essentially constant. The space-time diagram below . shows a dense region in blue on the left. ... The galaxies in the blue region are accelerating more just because the region is denser and therefore has higher gravitational forces. ... Tutorial : Part 1 | Part 2 | ...

... a major flood of the entire Upper Mississippi River basin which resulted in very wide spread agricultural and commercial damage.

... First of all, I should say that you cannot guarantee user-mode processes to have exact control of timing because of the multi-tasking nature of Linux. ... However, for most applications using I/O ports, this does not really matter. To minimise this, you may want to nice your process to a high-priority value (see the nice(2) manual page) or use real-time scheduling (see below). ... Linux 2.x kernels have soft real time support; see the manual page for sched_setscheduler(2) for details. ...
