. XMM-Newton Science Analysis System . testodf (testodf-0.45.1) [xmmsas_20080701_1801-8.0.0] . Meta Index / Home Page / Description . This test ODF is a simulation of an observation of a point source. The spectrum is a narrow Gaussian line at 1 keV. The source is located in an arbitrary location in the sky, and the spacecraft is initially pointing twoards the source. The spacecraft is drifting slowly away from the source and at the same time some jitter occurs. XMM-Newton SOC/SSC -- 2008-07-01

... They are concerned with Attitude Control System of the spacecraft, satellite visibility from tracking stations, limits on the satellite autonomous operations during the orbit, and needs for auxiliary operations with the spacecraft. ... Among the operational constraints the most important one is the number of programmed slews per orbit, which determines the maximum number of radio sources to be observed during one orbit. ...

... A new IRAF task has been developed that automatically identifies linear (line-like) features in an image or set of images. ... In order to automatically detect linear features, the first step is to select pixels in the image (Fig. 1 , left panel) that fall within a given data value range. ... Another aspect of extended linear features is that the image space pixels that describe them are in some way adjacent to one another and have a minimum and maximum length. ...

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): . ...

This diagram illustrates the effects of absolutely positioning a box with respect to the initial containing block. ... Most of the "inner" box contents are therefore rendered outside the document window. ... The text that is to the left of the line numbers lies outside the initial containing block.

... Launch Date: 1966-08-10 . ... The Lunar Orbiter 1 spacecraft was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions. ... The spacecraft was placed in a cislunar trajectory and injected into an elliptical lunar orbit for data acquisition. ... An 80-millimeter lens system was used to obtain Medium-Resolution (MR) photos, and a 610-millimeter lens system was used for High-Resolution (HR) photos. ...

... For observations we selected all Case galaxies in the zone = - from the Case lists III, IV, V, VIII, XI, XII and XIII which were classified in the Case survey by some indication on presense of [O III ] 4959,5007 emission lines (vs - very strong, s - strong, m - medium, w - weak, w? - weak?) and which had not been observed yet. ...

... I am an astronomer at the Australian National Universities' Research School of Astronomy and Astrophysics. We are located at Mount Stromlo Observatory, just outside of the Australian National Capitol, Canberra. The observatory has telescopes at two sites, one at Mount Stromlo, and the other near Coonabarabran. ... The work described here is not just my work, but the collective effort of more than 20 people from around the globe with whom I work on the High-Z SN search. ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ...
