... The identification criterion combines estimate of the wavelength of a line and an estimate of the error as well as a list laboratory wavelengths to determine and guarantee the identification of a given line. One could involve the additional knowledge of line strengths. But in practice this information of limited use, in reason of variations of relative line intensities caused by impurities, lamp ageing, pressure variations, a.s.o. Accordingly, the identification criterion is: . ...
