1 The present value of the proton-to-electron mass ratio is μ0=1836.1526670 (Mohr & Taylor 2000).
2 The damped Lyα systems are believed to originate in the intervening galaxies or proto-galaxies located at cosmological distances (e.g. Wolfe et al. 1995).
3 Based on the H2 laboratory wavelengths given in Abgrall & Roueff (1989).
4 The numbers shown in parenthesis are the 1σ standard deviations in the last digits after a decimal point.
