USNO Galilean observations
The New Astrometric Reduction of Old Observations (NAROO) program is dedicated to the measurement of astrophotographic plates and the analysis of old observations for scientific... -
Classifier catalogue of class II YSO posteriors
A naive Bayes classifier for identifying Class II YSOs has been constructed and applied to a region of the Northern Galactic Plane containing 8 million sources with good quality... -
GLADE+ (Galaxy List for the Advanced Detector Era)
We present GLADE+, an extended version of the GLADE galaxy catalogue introduced in our previous paper (Dalya et al., 2018MNRAS.479.2374D, Cat. VII/281) for multimessenger... -
SDSS quasar catalog, sixteenth data release (DR16Q)
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog... -
Extragalactic linear polarization meas. agglomeration
In the framework of the Standard Model Extension (SME), we present improved constraints on anisotropic Lorentz invariance and Charge-Parity-Time (CPT) violation by searching for... -
GLADE v2.3 catalog
We introduce a value-added full-sky catalogue of galaxies, named as Galaxy List for the Advanced Detector Era, or GLADE. The purpose of this catalogue is to (i) help... -
Second Byurakan Survey. General Catalogue
The Second Byurakan Survey (SBS) General Catalogue is presented. The SBS, a continuation of the Markarian survey reaching fainter limiting magnitudes, is the first survey which... -
Second Byurakan Survey galaxies. Optical database
A database for the entire catalog of the Second Byurakan Survey (SBS) galaxies is presented. It contains new measurements of their optical parameters and additional information... -
The SDSS-DR7 quasar catalog
We present the fifth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog, which is based upon the SDSS Seventh Data Release. The catalog, which contains 105783... -
SDSS-DR5 quasar catalog
The fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog, made from the SDSS Fifth Data Release, contains 77,429 objects; this is an increase of over 30,000... -
SDSS quasar catalog. III.
The catalog consists of the 46,420 objects in the SDSS Third Data Release that have luminosities larger than M_i_=-22 (in a cosmology with Ho=70km/s/Mpc, {Omega}M=0.3 and... -
Las Campanas Infrared Survey
The Las Campanas Infrared Survey, based on broadband optical and near-infrared photometry, is designed to robustly identify a statistically significant and representative sample... -
Catalogue of Seyfert Galaxies
A list of 959 Seyfert galaxies whose data were obtained up to the beginning of 1987 is compiled. Coordinates, redshifts, UBVR-photoelectric magnitudes, absolute magnitudes,... -
Southern Redshifts Catalogue
This catalogue provides a "best-estimate" of the heliocentric radial velocities of some 13000 galaxies south of Declination 0 degrees. It is based on over 17000 redshift... -
BV photometry of M11 stars
V-band time-series CCD photometric observations of the intermediate-age open cluster M11 were performed to search for variable stars. Cone search capability for table... -
Optical Imaging of 57 spiral galaxies
We present optical observations of a sample of 57 spiral galaxies and describe the procedures followed to reduce the data. We have obtained images in the optical B and I broad... -
Geneva stellar evolution tracks and isochrones
This database was created from an updated version of the empirically and semi-empirically calibrated BaSeL library of synthetic stellar spectra of Lejeune et al. (1997, Cat. ,... -
Photometric and Spectroscopic Databases for LSS Stars
This catalog contains databases of published photoelectric UBVbeta data, MK-system spectral classifications, and Stroemgren four-color uvby photometry for objects in the... -
Photometry and Proper Motions in M67
Relative proper motions were determined for 1068 stars with limiting magnitude b=16.5 and located within an area 130'*130' centered at alpha=8h 47.7m,delta=+12 deg.00' and... -
