Astrometry of Southern radio sources

Astrophysics and Space Science, 1991
An overview is presented of a number of astrometry and astrophysics programs based on radio sources from the Parkes 2.7 GHz catalogues. The programs cover the optical identification and spectroscopy of flat-spectrum Parkes sources and the determination of their milliarc-second radio structures and positions.

Astrometry with Radio Interferometers

2000
This chapter summarizes the principles and tools of radio astronomy that ultimately lead to the establishment of a fundamental catalogue via application of the technique of radio interferometry to the measurement of positions of sources at cosmological distances.

The Application of Radio Interferometers in Astrometry

International Astronomical Union Colloquium, 1975
AbstractAn account is given of the recent precision measurements of position of radio sources by VLBI and especially phase-stable interferometer systems of the 5 km radio telescope in Cambridge.A brief description of the 5 km. telescope is given as well as some of the remarkably accurate determinations of declination and right ascension of radio ...

Review of radio astrometry I. Radio measurements

International Astronomical Union Colloquium, 1978
At the astrometry symposium held at Perth in 1973, the radio astronomers devoted much of their allocated time towards explaining the techniques used in radio astrometry. As further details are available in, for example, the review by Counselman, it now seems appropriate to consider the achievements that have been made since the last symposium.
