Abstract : The Tycho-2 Catalogue presented here is an astrometric reference catalogue containing positions and proper motions as well as two-colour photometric data for the 2.5 million brightest stars in the sky. The Tycho-2 positions and magnitudes are based on precisely the same observations as the original Tycho Catalogue (hereafter Tycho-1) collected by the star mapper of the ESA Hipparcos satellite, but Tycho-2 is much bigger and slightly more precise, owing to a more advanced reduction…

Combined astrometric catalogue EOC-3 - An improved reference frame for long-term Earth rotation studies
Context. In the past, we collected the astrometric observations of latitude/universal time variations made worldwide at 33 observatories. These observations, re-analyzed with the Hipparcos Catalogue,
A pr 2 00 0 Comparing Tycho – 2 astrometry with UCAC 1
The Tycho–2 Catalogue, released in February 2000, is based on the ESA Hipparcos space mission data and various ground–based catalogs for proper motions. An external comparison of the Tycho–2
Star catalogue in the fields of axial meridian circle of the Nikolaev observatory
On the base of CCD-observations made with the axial meridian circle of the Nikolaev Observatory from 2008 to 2009, we compiled a catalogue for astrometric positions and proper motions for 140321
A CATALOG OF NORTHERN STARS WITH ANNUAL PROPER MOTIONS LARGER THAN 0".15 (LSPM-NORTH CATALOG)
The LSPM catalog is a comprehensive list of 61,977 stars north of the J2000 celestial equator that have proper motions larger than 015 yr-1 (local-background-stars frame). The catalog has been
Star catalog position and proper motion corrections in asteroid astrometry II: The Gaia era
Astrometric positions of moving objects in the Solar System have been measured using a variety of star catalogs in the past. Previous work has shown that systematic errors in star catalogs can affect
EARTH ORIENTATION PARAMETERS BASED ON EOC-4 ASTROMETRIC CATALOG
Recently we derived a new star catalog EOC-4 that contains not only the mean positions and linear proper motions, but also periodic changes, due to orbital motions, for double and multiple star

Abstract Astrometry is the basis for astronomical observations and measurements of coordinates and time. Its main task is to implement a reference frame—the one mentioned in Newton’s first law. Since
Problems of Using Hipparcos Astrometry of Double Stars
Abstract : The current optical realization of the International Celestial Reference System is the Hipparcos main catalog in its entirety. This paper demonstrates that a subset of the main catalog
Star catalog position and proper motion corrections in asteroid astrometry
Abstract We provide a scheme to correct asteroid astrometric observations for star catalog systematic errors due to inaccurate star positions and proper motions. As reference we select the most
