The movie demonstrates a succession of 7 complete measurement frames of SCA-1 on rotating Interball-1 spacecraft. Diagram, inspired by Salvador Dali's paintings, shows all 64 viewing directions and 15 energy steps as spheres. ... The distribution of spheres along viewing direction is linear unlike logarithmic distribution in reality. ... Complete 3-D distribution is measured for about 10s. Rotation of the spacecraft during one measurement frame is neglected. ...

COS Instrument Handbook for Cycle 24 . ... Cosmic Origins SpectrographInstrument Handbook for Cycle 24 > Chapter 5: Spectroscopy with COS > 5.9 COS Spectroscopy of Extended Sources . ... COS Spectroscopy of Extended Sources . COS spectra of extended objects can have significantly lower resolution than those of point sources, depending on the spatial distribution of the source. ... A similar situation arises when multiple point sources fall within the aperture. ...

... IRAF View . This is the orientation of the image as viewed in an image display via IRAF (e.g. ximtool, saoimage). Note: This is different from the orientation of the image as viewed on a Macintosh, via Remark . ... A +X, +Y instrument offset will move a star in the direction indicated by the arrows. ... Note: The offset direction depends upon which interface the offset command was issued in! ... Note: This is different from the orientation of the image as viewed by IRAF. ...

Magnetic field measurements onboard the Interball Tail spacecraft are carried out by the FM-3I instrument which consists of two flux-gate magnetometers covering two different ranges: [-200, +200] nT and [-1000, +1000] nT. Besides scientific goals, the FM-3I experiment data is used to perform the attitude control of the Interball Tail spacecraft. ... August 22, 1995 . ... October 18, 1995 . Top of the page . ...

... Archives . ... It refers to the spread in the measured energy of an incoming photon, and even astronomers often stumble over what it is and what it contains. ... The R edistribution M atrix F ile (RMF) is, at its most basic, a description of how the detector responds to incoming photons. ... The process of measuring the energy introduces a measurement error, which is encoded as the probability that incoming photons at energy E are read out in detector channels i . ...

GRANAT is the Russian x-ray sattelite launched to the high apogee orbit (200,000 km) and operated almost for 10 years (1989 -1999) , carrying out four major instruments: French SIGMA coded-mask hard x-ray telescope (30-1000 keV), Soviet ART-P coded-mask telescope (2??-60?? keV), all-sky monitor WATCH (6-150 keV), and a gamma-burst detector PHEBUS . ... Since September 1994, GRANAT is in the survey mode. ... Explore pages devoted to individual GRANAT instruments (including main scientific results): . ...

... Circinus is a nearby spiral galaxy only 4 degrees below the Galactic plane. ... Jones et al. (1996, in prep.) and Koribalski Whiteoak (1996) only recently mapped Circinus with several configurations of the ATCA; a few preliminary results are presented here. ... The elongated central disk (length about 5 arcmin) indicates a bar, and the central `hole' is caused by HI absorption against the bright central region of Circinus. ...

... A small yet powerful planning and scheduling toolkit has been built for the Submillimeter Wave Astronomy Satellite ( SWAS ) Small Explorer spacecraft. ... The simple design, minimal resource requirements and easy extensibility of the SWAS planning and scheduling toolkit should make it useful for other space astronomy missions. ... The relatively severe time and manpower constraints for the development of the SWAS Planning and Scheduling toolkit have forced it to remain small and simple. ...
