Abstract : This is a compilation of atomic lines with accurately known wavelengths covering the range from 15 A to 25000 A. The tables are a fairly complete record of available spectrum lines that meet the requirements for useful references with regard to wavelength accuracy and intensity. In general, wavelength uncertainties range from 0.0001 A to 0.002 A. Section 1, tau 2000 A, gives tau air and tau vac for 3341 lines belonging to thirteen different spectra of ten elements. Section 2, tau 2000 A, contains 2091 lines belonging to 59 different spectra of 28 elements. The lines of section 2 are listed both by spectrum (i.e. element and ionization stage) and in a finding list arranged in order of decreasing wavelength. Detailed explanations of the data and the sources used for the compilation are included. (Author)
