Abstract

The Ultraviolet Coronagraph Spectrometer (UVCS) of the Solar and Heliospheric (SOHO) mission has been developed for spectroscopic and polarimetric determinations of temperatures, densities and flow velocities in the extended solar corona. The instrument consists of two ultraviolet (UV) spectrometers and a visible light (VL) polarimeter. The grating of the UV channel optimized for the HI Lyman (alpha) (Ly-(alpha) ) line ((lambda) 1236 angstrom) and that for the OVI doublet ((lambda) (lambda) 1032/1037 angstrom) have been characterized.
