  • Spectrophotometric Atlas of Galaxies

    This catalog contains 56 spectra: 55 galaxy spectra, and one night sky spectrum, which is included for users wishing to check for low-level spurious features in the galaxy...
  • Spectrophotometric Atlas of Standard Stellar Spectra

    Continuous spectrophotometry has been obtained for 200 objects at a resolution of 10-17 A over the wavelength region 360-1000nm. Kron-Cousins BVRI colors are computed for the...
  • Intensity Distribution of Normal Stars

    Mean energy distributions are given for 98 normal stars in the spectral range from O to M and luminosity classes V, IV, III, II, and I. The points cover the wavelength range...
  • All-sky spectrally matched Tycho2 stars

    We present fitted UBVRI-ZY and u'g'r'i'z' magnitudes, spectral types, and distances for 2.4 million stars, derived from synthetic photometry of a library spectrum that best...
  • Spectrophotometry of 77 variable stars

    The results of visual and near-infrared spectrophotometric observations for 77 variable stars obtained during 1971-1991 in Chile, Armenia and Bolivia. The quasi-monochromatic...
  • Spectroscopic observations of southern stars

    The results of spectrophotometric observations of 64 southern stars in the range from 320 to 730nm are presented as quasi-monochromatic luminosities from the stars on the...
  • Spectrum of bipolar nebula AFGL 2688

    Based on echelle spectra obtained at the prime focus of the 6-m telescope, the detailed chemical composition of one of the components of the bipolar nebula identified with the...
  • Spectrum of IRAS 23304+6147

    Based on CCD-spectra obtain with the 6-m telescope, detailed chemical composition of the IR source IRAS 23304+6147 identified with the faint star is studied.
  • NIR fluxes for 35 HR late-type stars

    New semicontinuous scans (with nearly contiguous passbands) are presented for alpha CMi and for 24 G and K giants. In addition, 12 such scans published in 1984 are reduced to an...
  • Outer Galactic disk A and F stars space motions

    A and F stars can be used as probes of outer Galactic disk kinematics: here we extend the work of Harris et al. (2018, Cat. J/MNRAS/475/1680) by crossmatching their A/F sample...
  • Parameters of 1183 A and F stars

    Previous studies of the rotation law in the outer Galactic disc have mainly used gas tracers or clump giants. Here, we explore A and F stars as alternatives: these provide a...
  • M31 center emission-line point-like sources

    We present a detailed description of the wavelength, astrometric and photometric calibration plan for SITELLE, the imaging Fourier transform spectrometer attached to the...
  • ALHAMBRA fields type-I AGN with ELDAR

    We present ELDAR, a new method that exploits the potential of medium- and narrow-band filter surveys to securely identify active galactic nuclei (AGN) and determine their...
  • Faint emission lines in M16, M20, NGC 3603

    We present deep echelle spectrophotometry of the Galactic HII regions M16, M20 and NGC 3603. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle...
  • Spectrophotometry of the HII region S311

    We present echelle spectrophotometry of the Galactic H II region S311. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle Spectrograph in the...
  • Integrated Spectra of Open Clusters

    We present a library of 39 open cluster optical/near-IR integrated spectra. The data were obtained at CASLEO (San Juan, Argentina) and LNA (Itajuba, Brazil). Eight additional...
  • Methyl acetylene observations of warm clouds

    The results of a survey of 63 galactic star-forming region in the 6k-5k and 5k-4k methyl acetylene lines at 102.5 and 85.5GHz are presented. Fourty-three sources were detected...
  • Methanol maser condensations in W 48

    The methanol-line spectra in two maser condensations at velocities ~41 and ~45km/s in the star-forming region W 48 have been studied. Cone search capability for table...
  • Spectrophotometric standards near DE=+40{deg}

    The second stage to compile a list of regional intermediate-brightness spectrophotometric standards has been completed. It includes the spectral energy distribution for 24 stars...
  • Energy distribution of O9-B5 stars

    The normal spectral energy distribution for spectral subtypes from O4 to O8 and O9 to B5 for luminosity classes V,IV and III are derived. Three photometrically uniform catalogs...
