  • Interferometer phase calibration sources

    The catalogue contains compact radio sources with accurate positions observed with the Very Large Array (VLA). These sources are primarily intended for use as phase calibration...
  • 1400-MHz Sky Survey, Maps Covering Dec -5 to +82

    The survey contains 144 maps that cover the declination zone -5 to +82 degrees from the National Radio Astronomy Observatory (NRAO) 1400-MHz survey. The observations were made...
  • the FIRST Survey, version 1999Jul

    The FIRST survey to produce Faint Images of the Radio Sky at Twenty centimeters began in 1993. It uses the VLA (Very Large Array, a facility of the National Radio Observatory...
  • A Survey of Radio H II Regions in the Northern Sky

    Nearly 500 radio continuum sources near the Galactic plane at declinations greater than -37 degrees were examined for radio recombination line emission to see if they might be...
  • Fluxes of Faint Radio Sources at 2.7/4.75 GHz

    This table is a compilation of revised 4.75 GHz and 2.695 GHz flux densities and corresponding spectral indices at epoch 1986.2 of a catalog of 239 sources, which has previously...
  • Compendium of Radio Measurements of Bright Galaxies

    This catalog contains all radio measurements of optically bright 'normal' galaxies available up until publication of this compendium in 1975. The compendium was originally...
  • DRAO Penticton P-survey Database

    This catalog contains 1692 radio sources observed with the Penticton synthesis telescope at 408 MHz and at 1420 MHz. The catalog is comprised of sources detected in the...
  • 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...
  • The Green Bank Survey

    This catalog presents the parts I, II, and III of the Green Bank survey of extragalactic radio sources at 1400 MHz. The data were obtained with the 300' antenna, producing a...
  • The MIT-Green Bank 5GHz Survey

    The MIT-Green Bank 5GHz survey catalog was produced from four separate surveys with the National Radio Astronomy Observatory (NRAO) 91m transit telescope (Bennett et al.,...
  • the FIRST Survey, version 1998Feb

    The FIRST survey to produce Faint Images of the Radio Sky at Twenty centimeters began in 1993. It uses the VLA (Very Large Array, a facility of the National Radio Observatory...
  • VLA Survey of Rich Clusters of Galaxies

    We observed 60 fields towards 57 Abell and one Zwicky cluster of galaxies using the Very Large Array (VLA) with scaled arrays at 1.5 and 4.9 GHz. The source catalogue contains...
  • Bright Extragalactic Radio Sources (1Jy)

    The catalog is a compilation of 518 extragalactic radio sources with flux densities greater than 1 Jy at 5 GHz. It contains sources from the NRAO-MPI 5-GHz Strong Source Surveys...
  • The Zelenchuk Surveys

    The main catalog contains positions and flux densities for 8511 sources detected in the Zelenchuk 3.9 GHz Survey with declinations between 0 and 14 degrees. The survey was...
  • Molonglo deep sky survey of radio sources

    The observations for the MDS1 were made in Sep. 1973 over a period of 16 days, and consist of drift scans with the telescope set to one declination number (-20 and -62{deg})...
  • Southern flat-spectrum sources

    Optical identifications have been sought for 198 southern radio sources (73 in Paper I, 06h<RA(B1950)<18h and 125 in Paper II, 18h<RA(B1950)<06h) using new positions...
  • Miyun 232MHz survey

    A meter-wave survey of the sky region north of declination +30{deg} has been carried out with the Miyun Synthesis Radio Telescope (MSRT), Beijing Astronomical Observatory, at...
  • Radio survey of clusters of galaxies

    Observations of Abell clusters at 11.1, 6.2, 6.3 and 2.8cm with the 100m Effelsberg telescope. The data were compiled by H.J. Andernach. Cone search capability for table...
  • Texas Survey of radio sources at 365MHz

    We present the Texas Survey of discrete radio sources between -35.5deg and 71.5deg declination (B1950), which was carried out at 365MHz with the Texas Interferometer during...
  • The UTR-2 Very Low-Frequency Sky Survey Data

    The results of the very-low frequency (16.7MHz) survey of discrete sources made with the UTR-2 radio telescope is presented. The survey concerns the declination zones -13{deg}...
