Session 37 - First Results from the Solar and Heliospheric Observatory (SOHO).
Display session, Tuesday, June 11
The in-flight performance of the SOHO Ultraviolet Coronagraph Spectrometer (UVCS/SOHO) is consistent with the pre-launch characterization and meets all planned observational requirements. Measurements of the key UVCS/SOHO performance characteristics have been performed. This paper describes the measurement techniques and the results. In-flight values for the spectral and spatial resolutions, wavelength scales, the flat fields, the geometric distortions, radiometric calibrations, and stray light levels for the two ultraviolet channels have been determined. Comparisons will be made to pre-flight measurements at both the component level and system level. This work is supported by NASA under contract NAS5-31250 to the Smithsonian Astrophysical Observatory, by the Italian Space Agency and by Switzerland.
