VizieR Online Data Catalog: ASTRAL: reference spectra for evolved M stars (Carpenter+, 2018)

This paper focuses on the evolved cool stars γCru and αOri and compares their spectral characteristics to the well-studied K1.5III star αBoo (Hinkle+ 2005uaas.book.....H). The observational strategy for α Ori and γ Cru, as for the other objects in the ASTRAL Cool Star Program, was crafted to find the optimal combination of spectral resolution and signal-to-noise over the complete FUV and NUV spectra (1150-3159Å).

All of the HST Space Telescope Imaging Spectrograph (STIS) spectra for the two objects are splined in a top-level data set covering the entire wavelength region. An overview of the data used in this paper is presented in Table 1, and a more detailed description of the data, including the observing strategy, data reduction, coaddition, and splicing, can be found on the Advances Spectral Library (ASTRAL) website (http://casa.colorado.edu/~ayres/ASTRAL/) and at the Mikulski Archive for Space Telescopes (MAST) (http://archive.stsci.edu/prepds/astral/).
