  • Argentina High-Latitude H I Survey

    This survey consists of H I 21-cm spectra covering the southern sky with absolute galactic latitude |b|>10 degrees and a declination dec<-25 degrees. The observations were...
  • Parkes High-Latitude H I Survey

    This survey consists of HI 21-cm spectra covering the southern sky with absolute galactic latitude |b|>=10 degrees and declination dec<=-30 degrees. The observations were...
  • Northern HI Parkes All Sky Survey Catalogue (HIPASS)

    The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of...
  • Hat Creek High-Latitude H I Survey

    This survey consists of H I 21-cm spectra covering the entire northern sky with absolute Galactic latitude |b|>10 degrees and declination dec>-30degrees. The observations...
  • HI spectral properties of galaxies

    We present a homogeneous compilation of HI spectral parameters extracted from global 21cm line spectra for some 9000 galaxies in the local universe (heliocentric velocity...
  • Leiden/Argentine/Bonn (LAB) Survey of Galactic HI

    The LAB survey contains the final data release of observations of 21-cm emission from Galactic neutral hydrogen over the entire sky, merging the Leiden/Dwingeloo Survey (LDS:...
  • HI survey of the sky DE<+25{deg}

    We present the final data release of the high sensitivity {lambda}21-cm neutral hydrogen survey of the sky south of {delta}<=-25{deg}. A total of 50980 positions lying on a...
  • HI Parkes All Sky Survey Catalogue (HIPASS)

    The HI Parkes All-Sky Survey (HIPASS) Catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4315 sources identified purely by their HI content. The...
  • Huchtmeier-Richter HI catalog

    The catalog contains all published HI observations (21cm) of external galaxies published until the middle of 1988. It contains almost 20,000 entries for over 10,000 galaxies...
  • Atlas of Galactic Neutral Hydrogen

    The Leiden/Dwingeloo HI survey mapped the 21-cm spectral line emission over the entire sky above declinations of -30 degrees using a grid spacing of ~ 0.5 degree and a velocity...
  • Bell Laboratories H I Survey

    The sky north of declination -40{deg} was observed in the 21cm line of atomic hydrogen with the FWHM=2{deg} beam of the 20 foot horn reflector at AT&T Bell Laboratories,...
  • Berkeley Low-Latitude H I Survey

    This survey consists of H I 21-cm spectra covering galactic latitudes from -10 degrees to +10 degrees and galactic longitudes from 10degrees to 250degrees. The observations were...
  • Bell Laboratories H I Profiles

    This survey consists of H I 21-cm spectra covering galactic latitudes |b|>10degrees, North of Declination -40deg, observed with the 20-foot horn reflector at AT&T Bell...
  • HYPERLEDA. II. Homogenized HI data

    After a compilation of HI data from 611 references and new observations made in Nancay, we produce a catalog of homogenized HI data for 16781 galaxies. The homogenization is...
  • Mark III Catalog of Galaxy Peculiar Velocities

    Tully-Fisher and Dn-sigma distances, radial velocities, and associated catalog and observational data for the spiral, irregular, and elliptical galaxies that comprise the Mark 3...
  • HI observations of flat galaxies

    Results of HI observations with the 100-m Effelsberg radio telescope are presented for 94 edge-on spiral galaxies from the Revised Flat Galaxy Catalog (Karachentsev et al.,...
  • FUGIN. VII. Galactic plane HI clouds

    We analyze molecular-gas formation in neutral atomic hydrogen (HI) clouds using the latest CO data, obtained from the FOREST (four-beam receiver system on the 45m telescope)...
  • The FAST all sky H I survey (FASHI)

    The FAST All Sky HI survey (FASHI) was designed to cover the entire sky observable by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), spanning approximately...
  • Magellanic Clouds bridge region HI profiles

    Two hundred and seventeen HI profiles at positions approximately 1degree apart in the bridge region between the Small and Large Magellanic Clouds have been observed with a 15'...
  • Velocities of RFGC galaxies

    A list of radial velocities, HI line widths and peculiar velocities of 1327 galaxies from the RFGC catalogue has been compiled using actual observations and literature data. The...
