[25.04] CoolCAT

T.R. Ayres (CASA)

\noindent CoolCAT is a cool-star UV spectral catalog derived from the rich stellar archive of STIS E140M/H and E230M/H exposures. There are approximately 50 more-or-less normal late-type stars in the {\em HST}~STIS archive with at least one E140M spectrogram, providing full UV wavelength coverage from 1150--1700~Å\ at a resolution of R\equiv \lambda/\Delta\lambda~4\times104. About 70% of these stars also have one or more E230M/H exposures, covering all, or part, of the interval 1700--3000~Å. Approximately 150 E140M exposures have been reduced for CoolCAT, and a comparable number of E230's, split nearly equally between the medium-res (M: R~3\times104) and high-res (H: R~1\times105) modes. CoolCAT consists of a collection of digital spectral atlases---echellograms processed to the same uniform standard, multiple observations graded and coadded, and adjacent wavelength regions concatenated---and a supporting catalog of line identifications, wavelengths, widths, and fluxes. Semiautonomous line fitting procedures ensure a homogeneous and uniform treatment of the diverse spectral material. A wide range of investigations---from the photochemical evolution of primitive planetary atmospheres, the dynamics of cool star atmospheres, to galactic population synthesis---will be enabled by CoolCAT. The database will reside at the Multimission Archive at Space Telescope (MAST).\\[-3mm]
