A Nonlinear Least Squares Method of Determining Line Intensities and Half-widths

Volume 31, Number 3 (June 1977) Page 213-220

Chang, Y.S.; Shaw, J.H.


A nonlinear least squares method of retrieving line intensities and half-widths from spectra degraded by a finite instrumental resolving power is discussed. Examples of the applications of this technique to obtain the parameters of a single isolated line and of an overlapping pair of lines are presented.
