The XZ catalog was created at the U.S. Naval Observatory in 1977 by Richard Schmidt and Tom Van Flandern, primarily for the purpose of generating predictions of lunar...

The NPM2 Catalog is the second part of the Lick Northern Proper Motion (NPM) program to measure absolute proper motions, on an inertial system defined by distant galaxies, for...

The UCAC2 Bright Star Supplement (UCAC2 BSS) is meant to be used with the Second U.S. Naval Observatory CCD Astrograph Catalog (UCAC2, CDS Catalogue number ) to fill in the...

The USNO-B1.0 is a catalog that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,045,913,669 objects derived from...

Into the present catalogue the seasonal mean relative positions (rho and theta 2000) are included for 234 visual double stars observed at Pulkovo with 26-inch refractor from...

The UCAC2 is the second release of the ongoing UCAC project, designed to observe the entire sky for R magnitudes of about 7.5 to 16. The observed positional errors are about 20...

A catalogue of positions and proper motions of 58483 stars (Pul-3) has been constructed at the Pulkovo observatory. The Pul-3 is based on the results of measurements of the...

The Naval Observatory Merged Astrometric Dataset (NOMAD) contains astrometric and photometric data for over 1 billion stars derived from the Hipparcos (I/239), Tycho-2 (I/259),...

The Carlsberg Meridian Telescope (formerly the Carlsberg Automatic Meridian Circle) is dedicated to carrying out high-precision optical astrometry. It underwent a major upgrade...

The catalogue contains 2601 stars obtained in the course of observational campaign of the KSZ programme that is the Russian abbreviation, which stands for the catalogue of faint...

We present the astrometric catalogue of faint reference stars in 255deg^2^ sized fields with ICRF objects of northern hemisphere. The XC1 is based on our results of measurements...

The GSC II is an all-sky catalog based on 1" resolution scans of the photographic Sky Survey plates, at two epochs and three bandpasses, from the Palomar and UK Schmidt...

The catalogue contains 5969 southern reference stars (SRS) and 726 bright stars (BS). The observations were carried out in the declination zone from 0{deg} to -20{deg} with the...

We present the CdC2000 catalogue issued from the reduction of the complete Bordeaux Carte du Ciel zone observed at the beginning of last century with the Bordeaux astrograph....

This catalog contains the results of the differential observations of 3939 stars made with the Transit Circle of the Bucharest Observatory, from 1955 July 1 to 1962 June 16. The...

The catalogue contains 5954 stars obtained in the course of observational campaign of the AGK1 programme that is the German abbreviation, which stands for the catalogue of...

A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than magnitude Hp=8 to be...

The results of new reduction of 1545 photographic observations of 14 selected asteroids' obtained with Normal Astrograph of Pulkovo observatory from 1948 to 1990 years...

USNO-B1.0 (Cat. I/284) and 2MASS (Cat. II/246) are the most widely used full-sky surveys. However, 2MASS has no proper motions at all, and USNO-B1.0 published only relative, not...

The SPM4 Catalog contains absolute proper motions, celestial coordinates, and B,V photometry for 103,319,647 stars and galaxies between the south celestial pole and -20 degrees...
