Analysis of the solar spectrum using Voigt profiles

The mathematical method we formerly used for decomposing the solar spectrum into Gaussian components is now generalized so as to include Voigt profiles. This method is applied to a theoretical blend of Voigt profiles. Gaussian approximations are also examined in some detail. Only the knowledge of the observed wings of a line to a sufficiently great extent can lead to reliable values for the parameters of a Voigt profile.Steyaert Herman, Dingens Paul, Baeck Nicole.
