  • Far-UV excess object survey

    Optical spectra have been obtained for a selection of objects included in a catalog of far ultraviolet bright, high galactic latitude objects detected with a balloon-borne...
  • SKYLAB S-019 Far-UV Objective-Prism Spectrophotometry

    The catalog contains the ultraviolet flux measurements at wavelengths of 130-420nm, obtained with an objective-prism telescope during the three manned Skylab missions (Skylab 2,...
  • IUE Low-Dispersion Reference Atlas I, Normal Stars

    The atlas contains the fluxes (2 angstroms/step) of 229 low-dispersion stellar spectra collected by the International Ultraviolet Explorer (IUE) satellite, compiled for the...
  • Copernicus 0.2-A Resolution Far-UV Stellar Spectra

    The catalog is a subset comprising data for 60 O- and B-type stars observed by the Copernicus satellite. For each star a FITS file was created of the observed spectrum. Each...
  • Stars classified from S2/68 UV line features

    This catalog provides the spectral classifications of 1900 stars from the papers listed in References. The classifications were made from spectra obtained by the S2/68 sky...
  • UV Bright Star Spectrophotometric Catalog

    This catalogue contains observations carried out by the S2/68 Ultraviolet Sky Survey Telescope (UVSST) aboard the ESRO Satellite TD-1, which measured the absolute ultraviolet...
  • Astron low resolution UV spectra

    Astron was a Soviet spacecraft launched on 23 March 1983, and it was operational for eight years as the largest ultraviolet space telescope during its lifetime. Astron's payload...
  • Catalog of Eq.Widths of Interstellar 217nm Band

    (from CDS Inf. Bull. 40, 31) The main task of the catalogue consists in a comprehensive collection of equivalent widths of the 217nm band derived from both spectrophotometric...
  • An Ultraviolet Atlas of Quasar and Blazar Spectra

    This atlas contains the ultraviolet spectra of 70 quasars, blazars, and Seyfert 1 galaxies that were produced by combining over 100 low resolution spectra from the International...
  • Wavelength Dependence of Galactic UV Extinction

    A collection of data for 115 extinction curves derived from low-dispersion IUE spectra are presented with normalization to E(B-V)=1. The electronic Atlas of Extinctions contains...
  • IUE Atlas of O-Type Stellar Spectra

    The International Ultraviolet Explorer Atlas of O-Type Spectra From 1200 to 1900 A (Walborn et el. 1985) lists normalized fluxes and flux quality factors, splice points, and...
  • A Finding List of Faint UV-Bright Stars

    The survey lists the very blue objects found on the plates taken for the Sandage Two-Color Survey of the Galactic Plane obtained using the Palomar 48 inch Oschin Schmidt...
  • A Finding List of Faint UV-Bright Stars

    195 UV-bright stars have been found on two-color 48-inch Schmidt plates centered on the galactic plane, and on one high-latitude plate. This catalog contains sources with (U-B)...
  • Population Synthesis Models at very low metallicities

    Using new sets of stellar evolution models at very low metallicities (Z=10^-7^; 10^-5^) and previously published grids we examine spectral properties of the ionising continua,...
  • EUVE optical atlas

    The Extreme Ultraviolet Explorer (EUVE) has been detecting EUV sources since its launch in June 1992. Positions of 540 sources have been made available to the community by the...
  • Study of 230 IRAS-FSC galaxies

    From the cross-correlation of the IRAS FSC catalog with the radio FIRST catalog, 230 infrared galaxies were selected having optical classifications and redshifts from SDSS and...
  • U-SMAC I. UV catalog of SMC-Shell region

    The interactions between the Magellanic Clouds significantly affect the shape and distribution of the young stellar population, particularly in the periphery of the Small...
  • HII-CHI-Mistry-UV for AGN. Abundances

    We present an adapted version of the code HII-CHI-mistry-UV (Perez-Montero & Amorin, 2017MNRAS.467.1287P) to derive chemical abundances from emission lines in the...
