Notes. Frequencies and molecular data are taken from the Cologne Database for Molecular Spectroscopy (Müller et al. 2001).
α is defined as the conversion factor between integrated opacity and total column density Ncol = α × ∫τdv, calculated under the assumption that the rotational excitation is coupled with the cosmic microwave background temperature, 5.14 K at z = 0.89 (see, e.g., Muller et al. 2013).
Integrated opacity, over the velocity interval [−20;+20] km s-1. The associated uncertainty is of 0.003 at 1σ.
