General Catalogue of Herbig-Haro Objects
Herbig-Haro (HH) objects are small-scale shock regions intimately associated with star forming regions. The present catalogue includes for all known HH objects: the HH number,... -
Plate Centers of POSS-II
The catalog contains the coordinate of the plate centers forming the Second Epoch Palomar Oschin Schmidt Sky Survey (POSS-II), observed between 1985 and 2000, and covering the... -
Digitized First Byurakan Survey plate database
(no description available) Cone search capability for table VI/116/dfbs (The Digitized First Byurakan Survey (DFBS) plate database) -
POSS Plate Data
This catalog contains plate-center and observational data for all plates of the National Geographic Society and Palomar Observatory Sky Survey (POSS) and its Whiteoak Extension.... -
Plates of the ESO / SERC Sky Survey
The "ESO/SRC Atlas of the Southern Sky" is a major tool for, among other things, the optical identification of sources in non-optical wavelengths. The catalog contains the... -
Wide-Field Plate Database
The Wide-Field Plate Database (WFPDB) contains the descriptive information for the astronomical wide-field (~>1deg.) photographic observations stored in numerous archives all... -
Surface Photometry of ESO-Uppsala Galaxies
The 15467 southern galaxies in this catalog were scanned from 407 blue and 407 red original ESO-Schmidt plates using a PDS microdensitometer. The galaxies were selected from the... -
Rich Clusters of Galaxies
This is an all-sky catalog of 4073 rich clusters of galaxies, each having at least 30 members within the magnitude range m_3_ to m_3_ + 2 (m_3_ is the magnitude of the third... -
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... -
Most massive stars and their clumped winds
The star cluster R136 inside the Large Magellanic Cloud hosts a rich population of massive stars, including the most massive stars known. The strong stellar winds of these very... -
Gaia EDR3 and Johnson-Kron-Cousins standards
In the era of large surveys and space missions, it is necessary to rely on large samples of well-characterized stars for inter-calibrating and comparing measurements from... -
Milky Way low mass young stars from Gaia EDR3
With an unprecedented astrometric and photometric data precision, Gaia EDR3 provides, for the first time, the opportunity to systematically detect and map, in the optical bands,... -
The VLBA Galactic Plane Survey (VGaPS)
We presents accurate absolute positions from a 24 GHz Very Long Baseline Array (VLBA) search for compact extragalactic sources in an area where the density of known calibrators... -
Galaxies in Lynx-Cancer void
In this work we present the results of photometrical study of 85 objects from the updated sample of galaxies residing in the nearby Lynx-Cancer void. The images in filters...
