M02    W. C. Martin, ongoing compilation of data for He I (2002). This work includes an updating of the energy-level data in [M87]. The uncertainty of the excited-level system and limit with respect to the ground level is about 0.002 cm-1 [EUVH97, BBBL98]. References for most of the more recent experimental data are given in [DM98]. Some level separations are known to six or more decimal places, but have here been rounded to four places. The values for some levels are derived from recent theoretical calculations [D03]. The wavelengths are calculated from the energy levels. The estimated uncertainty of the wavelengths of the resonance lines given to five places (507-591 Å) is at most one unit in the fifth place.
