The data were obtained with ESO's Kueyen telescope equipped with the UVES spectrograph on March 9/10, 11/12, 13/14 in 2009. The instrument was operated in dichroic mode (spectral coverage from 3290 to 4500 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): Absolute errors are about a factor of 2, differential errors are much smaller Note (2): Line identification status as follows: 0 = secure line identification 1 = unsecure line identification (mostly due to single line out of multiplet) 2 = single line out of multiplet but secure identification, since line was secure identified in the megaflare of CN Leo Note (3): Abbreviations used: em = emission line core in absorption line NIST = line was identified using NIST no gaussian = line is fitted poorly by a Gaussian, flux has large errors
