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
