Abstract:
Flares on dM stars contain plasmas at very different temperatures and
thus affect a wide wavelength range in the electromagnetic spectrum.
While the coronal properties of flares are studied best in X-rays, the
chromosphere of the star is observed best in the optical and
ultraviolet ranges. Therefore, multiwavelength observations are
essential to study flare properties throughout the atmosphere of a
star.
Description:
We present an extensive identification catalog of chromospheric
emission lines in the optical range for a giant flare on CN Leonis.
The data were obtained with ESO's Kueyen telescope equipped with the
UVES spectrograph on May, 19th/20th, 2006. The instrument was operated
in dichroic mode (spectral coverage from 3050 to 3860 and from 6400 to
10080Å). 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 identification status as follows:
0 = secure line identification
1 = probable line identification
2 = supplementary (weak) line (for completion of multiplet)
3 = poorly decomposed line, possibly additional lines existent
4 = no identification possible
5 = line measured in flare-only spectrum, secure identification
6 = line measured in flare-only spectrum, probable identification
7 = singlet line/single line from multiplet, but secure identification
Note (2): Some abbreviations are used:
n = line not measured in flare on LHS 2034 as found in J/A+A/439/1137
no gauss = line has no Gaussian shape, therefore flux poorly determined
gauss affected = line in wing of non-Gaussian line: flux poorly determined
NIST = identification from NIST catalog
blend = gives alternative identification of line
