Astrometry with Radio Interferometers,on of the technique of radio interferometry to the measurement of positions of sources at cosmological distances. With this target in mind we briefly introduce the scope of radio astronomy, followed by a short outline concerning the basic terms and concepts of radio interferometry.

The International Celestial Reference Frame: ICRF, belongs to the category of conventional fundamental catalogues. It does not differ fundamentally from the numerous radio catalogues produced during the preceding two decades. This catalogue is merely another member of the category of reference frames produced by the `observable method’ discussed in作者: Interlocking 時(shí)間: 2025-3-22 17:15 作者: 騷動(dòng) 時(shí)間: 2025-3-23 00:58
