VizieR Online Data Catalog: ASTRAL: abundance analysis of HR 465 (Nielsen+, 2020)
Abstract
The ASTRAL: Hot Stars Treasury Program was designed to achieve the ultimate combination of high spectral resolution and signal-to-noise over the far- and near-ultraviolet spectrum. The spectrum of HR465 covers the wavelength interval between 1150 and 3047Å and is composed of 21 coadded and merged individual recordings. The spectral resolution shortward of 2334Å is R~30000; however, for wavelengths below 1600Å the spectrum is modeled with a lower value (R~25000) to achieve a better match to the observation. For wavelengths above 2350Å the spectral resolution is ~117000.
