Description:
We present a identification catalog of chromospheric emission lines in
the optical range for two flares on AB Dor A, with event 1 being
larger than event 3. An additional flare event 2 is not described here
because of its overlap with event 1. All lines are identified in an
flare- only spectrum, i.e. with a quiescent spectrum subtracted. The
data were obtained with ESO's Kueyen telescope equipped with the UVES
spectrograph on November 25/26 in 2009. The instrument was operated in
dichroic mode (spectral coverage from 3720 to 4945 and from 5695 to
9465 AA). We tabulate measured wavelength, line flux and FWHM for
every line and also provide the rest wavelength from the Moore catalog
which was used for identification (Moore, 1972, Nat. Stand. Ref. Data.
Ser., 40). Few lines were identified with the NIST database.

Note (1): Line fluxes are given in arbitrary units, since no absolute flux
calibration was possible and a quiescent spectrum is subtracted after
normalization
Note (2): Abbreviations used:
NISTl = line was identified using NIST
not in CN Leo list = the line is not listed in VizieR in
J/A+A/487/293/table1 (Fuhrmeister et al. 2008)
not in ProxCen list = the line is not listed in VizieR in
J/A+A/534/A133/table6 (Fuhrmeister et al. 2011)
line not fitable = line cannot be fitted with a single Gaussian,
but is clearly there
