J/A+A/376/28       Inversion of the HE 1122-1648 UVES spectrum  (Rollinde+ 2001)

Physical properties and small-scale structure of the Lyman-alpha forest: Inversion of the HE 1122-1648 UVES spectrum. Rollinde E., Petitjean P., Pichon C. <Astron. Astrophys. 376, 28 (2001)> =2001A&A...376...28R
ADC_Keywords: QSOs ; Spectroscopy Keywords: methods: data analysis - methods: N-body simulations - methods: statistical - galaxies: intergalactic medium - galaxies: quasars: absorption lines - cosmology: dark matter 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).

2- 8 F7.2 0.1nm lambda Position of the line 13- 18 F6.2 km/s b Doppler parameter 23- 29 F7.4 [cm-2] logNVPFIT *Column density 1 35- 41 F7.4 [cm-2] logNdelta *Column density 2
Note on logNVPFIT : logarithm of the column density as fitted by an automatic Voigt profile procedure (Carswell et al., 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 for details)
