Journal ArticleDOI
The International Celestial Reference Frame as Realized by Very Long Baseline Interferometry
Chopo Ma,E. F. Arias,T. M. Eubanks,A. L. Fey,A. M. Gontier,Christopher S. Jacobs,Ojars J. Sovers,B. A. Archinal,Patrick Charlot +8 more
TL;DR: A quasi-inertial reference frame is defined based on the radio positions of 212 extragalactic sources distributed over the entire sky as discussed by the authors, which is better than about 1 mas in both coordinates.

TL;DR: The second realization of the International Celestial Reference Frame (ICRF2) at radio wavelengths is presented, adopted by the International Astronomical Union as the new fundamental celestial reference frame, replacing ICRF1 as of 2010 January 1.
Journal ArticleDOI
The Second Extension of the International Celestial Reference Frame: ICRF-EXT.1
A. L. Fey,C. Ma,E. F. Arias,Patrick Charlot,M. Feissel-Vernier,A. M. Gontier,Christopher S. Jacobs,Jinling Li,Daniel MacMillan +8 more
TL;DR: This paper used very long baseline interferometry data obtained between mid-1995 and the end of 2002 May together with older data to extend and revise the International Celestial Reference Frame (ICRF).
Journal ArticleDOI
A Radio Reference Frame

TL;DR: In this paper, the authors presented a catalogue based on the radio positions of 436 extragalactic sources distributed over the entire sky, with the positional accuracy of the sources is better than 3 milliarcsec (mas) in both coordinates.
