HIGH RESOLUTION SPECTRA OF THE SUN,
Abstract
The University of Liege is operating, since 1958, a laboratory of solar spectroscopy at the International Scientific Station of the Jungfraujoch (Switzerland). During the last years, much effort has been devoted in two main directions: (a) techniques of correction for the effects of the instrumental function to obtain the best possible knowledge of central intensities and profiles of photospheric lines. (b) increase of the signal to noise ratio in the records in order to detect and measure very faint absorption features. In addition, a balloon-borne equipment is now under construction in Liege to observe, with maximum resolution, the near infrared solar spectrum from an altitude of about 80,000 feet. (Author)
