Description:
This Table contains parameters of 655 spectral features in the
spectrum of eta Carinae, in the wavelength region 3850-11000
Angstrom. The narrow and broad line components were measured
separately, for the spectrum in high excitation state (year 1995) and
during the "spectroscopic event" of June/1992. The spectra were
collected at ESO (Chile) and LNA (Brazil) at high resolution. Several
spectral lines of Fe II, [Fe II], [Fe III], [N II] ands Ca II are
identifyed for the first time in the spectrum of this star. Line
variability between high and low excitation states is characterized in
an objective way (parameter var in the last column).

Note (1): ]: For lines that have no identification, the observed wavelength
was corrected by the radial velocity of the object (-40 km/s) in
order to indicate the expected laboratory wavelength.
Note (2): This is equal to the equivalent width in Angstrom for lines seated on
the stellar continuum.
Note (3): Defined in equation (1) - see text
