Description
A high-resolution optical spectrum of EX Lupi was obtained on 2007 July 30 with FEROS at the 2.2m MPG/ESO telescope in ESO La Silla, Chile. The spectrum shows several emission lines in addition to the photospheric absorption features characteristic of the young late-type star. Here we present all emission lines identified in the spectrum, the observed wavelengths and equivalent widths in Angstrom and the full widths at half maximum in km/s, determined by Gaussian fitting. The most prominent emission lines are the Balmer lines of the hydrogen, the H and K lines and the infrared triplet of the ionized calcium, and the helium lines at 5875 and 6678 Angstrom, and in addition more than 200 weak, narrow metallic lines could be identified using Moore's (1945, Contrib. Princeton Univ. Obs., No. 20) multiplet tables. (1 data file).

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
