Position difference vectors and of the jets
We aim to study the relative positions of quasar emission centers at different wavelengths in order to help link the various realizations of the International Celestial... -
Stability of VLBI reference frame
The file table 2 gives the results of various tests and noise measurements performed on time serie of extragalactic radio source coordinates. Systematic and random behaviours in... -
Bibliography of stellar radial velocities
The data file contains a bibliography of 44,000 radial velocities for about 25,000 stars, from a compilation of about 2340 publications (see the "Note (3)" below). The authors... -
Stellar radial velocities bibliographic catalog
The present catalogue is the twelfth version and the continuation of the first one (1991-1994) published by Malaroda et al. (2000A&AS..144....1M). Since the 2005 version, we... -
Stellar Radial Velocities 1991-1998
The present catalogue is the third version and supersedes the first one (1991-1994) published by Malaroda et al. (2000A&AS..144....1M, Cat. ). We have revised the issues of... -
Stellar radial velocities bibliographic catalog
We present a bibliographic catalogue of stellar radial velocities with 13359 entries for stars in the Galaxy and the Magellanic Clouds, obtained from the issues of several... -
A Reference List for the UBV System
This catalog is a file of 13422 records giving for each star, an identification, V, B-V, and U-B. Care was taken to place all measurements on the Johnson UBV system by... -
Guide Star Photometric Catalog V2.4
We publish 1653 CCD photometric sequences in the Johnson-Kron-Cousins standard system, distributed both in the northern and southern hemispheres, useful for the calibration of... -
Guide Star Photometric Catalog, Updated Version 1
The Guide Star Photometric Catalog (GSPC) is an all-sky set of 1477 photoelectrically determined BV sequences covering the magnitude range from 9 to 15. The GSPC was created to... -
New Reference Frame defined by Extragalactic Radio Source
This is the annex to Resolution B5 of the XXII Assembly of the IAU. This list of extragalactic objects identifies sources which define the new conventional celestial reference... -
Spectroscopically identified white dwarfs
This is an update of the Villanova catalog published in the ApJS paper, corresponding to the Web version of the catalog in Apr 2014 (see... -
Kinematics and HR Diagrams of Southern Young Stars
We investigate the spatial distribution, the space velocities and age distribution of the pre-main sequence (PMS) stars belonging to Ophiuchus, Lupus and Chamaeleon star-forming...
