Method of spectral wavelength calibration using the VALD database
Abstract
A method for identifying spectral lines in the spectra of hollow cathode lamps with limited accuracy of preliminary wavelength calibration is presented. The method is based on a statistical analysis of the set of possible spectral lines of various chemical elements from the VALD database in the vicinity of the lamp spectral lines. The application of the method, which significantly improves the calibration accuracy, is illustrated using the spectra of two lamps.
