... Several composite flatfields (superflats) have been generated from all Eng. 4 flatfield observations. After removing the LED pattern, these superflats where used to identify OM bad pixels. These badpixels are real physical pixels, thus include 8x8 subpixels. ...

... The unexpected discovery of Jupiter-size planets very close to their parent stars (two examples of which are 51 Peg and Boo) creates a challenge for theories of planetary formation and structure. ... Direct observation of such extra-solar planets with an infrared interferometer is a difficult task because of the very high dynamic range required (typically 3?104 to 3?105), but not impossible if a very careful spatial filtering and calibration is imposed upon the recombined beams. ...

What: GOCG generates the Space Radio Telescope (SRT) schedule file, or SRS file, from current GSTS file. The SRS file has more precise time stamps than long-term schedules, and also designates which GTS will be used when. ... The SRS file also serves as the antenna pointing schedule file, as it describes the planned orientation of the spacecraft (and solar panels) as a function of time. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
