TL;DR: The Coronal Diagnostic Spectrometer (CDS) as mentioned in this paper was designed to probe the solar atmosphere through the detection of spectral emission lines in the extreme ultraviolet wavelength range 150-800 A. By observing the intensities of selected lines and line profiles, the authors derived temperature, density, flow and abundance information for the plasmas in the solar ionosphere.

TL;DR: The ROSAT project is an international collaboration between the Federal Republic of Germany, the United Kingdom, and the United States as mentioned in this paper, which carries a payload of two coaligned imaging telescopes: the German X-Ray Telescope (XRT) which operates in the soft x-ray band (0.1 to 2 keV or 6 to 100 A).
Proceedings ArticleDOI
First in-orbit measurements with the ROSAT XUV wide field camera
Alan A. Wells,A. F. Abbey,Martin A. Barstow,Richard E. Cole,John P. Pye,Mark R. Sims,J. E. Spragg,Darach Watson,Richard Willingale,G. M. Courtier,James D. Gourlay,B. J. Kent,A. G. Richards,J. S. Wright,C. V. Goodall,E. R. Breeveld,Howard E. Huckle,A. J. McCalden,T. J. Sumner +18 more
TL;DR: The main design features and early findings of the Rosat XUV wide field camera (WFC) are discussed in this article, where the most important data on the WFC telescope and detectors are presented.
Journal ArticleDOI

B. A. Cooke,Martin A. Barstow,E. R. Breeveld,P. A. Charles,C. V. Goodall,J. A. Gourlay,B. J. M. Hassall,H. E. Huckle,B. J. Kent,John P. Pye,A. G. Richards,Mark R. Sims,T. J. Sumner,M. G. Watson,Alan A. Wells,Richard Willingale,J. S. Wright +16 more
TL;DR: In this article, the discovery of a new white dwarf as a bright extreme ultraviolet (EUV) source was reported during the first observations using the Wide Field Camera1 on the Rosat satellite.
Journal ArticleDOI

TL;DR: In this article, a preliminary observation of a small section of the sky, carried out over July 11-16 (the mini-survey) showed all ROSAT systems to be functioning well and has allowed predictions to be made on the ultimate productivity of both ROSAT all-sky surveys.
