Description
The ratio of the intensities is related to the emph{equivalent width}, W, of the spectral lines, which shape is approximated to a Voigt function resulting from the convolution of a Lorentzian (Stark and Van der Waals effects) and Gaussian (Doppler effect and optical broadening) profiles. Thus, we have studied the influence of the self-absorption over W in different plasma column lengths.
