Description:
File tablea1.dat contains the list of the Lyman-α absorption
lines identified in the spectrum of HE 1122-1648 obtained during
Science Verification of UVES at the VLT. We used the standard method
of Voigt Profile fitting with VPFIT and with the inversion method
described in the related paper.
(Note that the printed version of the paper indicates HE 1122-1628,
instead of the quasar HE 1122-1648).

Note on logNVPFIT :
logarithm of the column density as fitted by an automatic Voigt profile
procedure (Carswell et al., 1987ApJ...319..709C 1987ApJ...319..709C)
Note on logNdelta :
logarithm of the column density as derived from the Bayesian inverted density
(see paper and Pichon et al. 2001MNRAS.326..597P 2001MNRAS.326..597P for details)
