Reference Frame (ICRF), named ICRF2 is the current radio catalog, which contains accurate celestial positions of 3414 compact radio sources (extragalactic radio sources and quasars), …

The International Celestial Reference Frame (ICRF) based on the VLBI-derived positions of 608 extragalactic radio sources was adopted by the International Astronomical Union (IAU) in 1998 …

The ICRF (Ma et al. 1998) was the first all-sky realization of an extragalactic frame with milliarcsecond (mas) position accuracy and the first realization of the International Celestial …

Oct 26, 2020 · This new realization, referred to as ICRF3, is based on nearly 40 years of data acquired by very long baseline interferometry. The ICRF3 includes positions at 8.4 GHz for …

Jul 7, 2022 · Accurate measurement of angular positions on the sky requires a well-defined system of reference that is realized with accessible objects. The purpose of this study is to …

The radio source catalogue which was adopted as the official International Celestial Reference Frame (ICRF) by the IAU at its General Assembly in 1997 belongs to the category of …
