Scientific paper

It is well known that IUE high resolution spectra suffer essentially of a low signal to noise (S/N) ratio. In an attempt to improve the situation, the authors have used the data analysis and restoration method recommended by Brault and White (05.021.008), a detailed application of the classical "optimum filter" technique based on Fourier transforms. The authors describe shortly how they did apply the Brault and White precepts, which particuliar cautions were taken, and through the results of further spectroscopic analysis involving curve of growth techniques, the authors show that the quality obtained is pretty good.
