Cambridge Low Frequency Synthesis Telescope
Encyclopedia
The Cambridge Low-Frequency Synthesis Telescope (CLFST) is an east-west aperture synthesis
radio telescope
currently operating at 151 MHz. It consists of 60 tracking yagis
on a 4.6 km baseline, giving 776 simultaneous baselines. These provide a resolution of 70×70 cosec(declination) arcsec2, with a sensitivity of about 30 to 50 mJy/beam, and a field of view
of about 9°×9°. The telescope is situated at the Mullard Radio Astronomy Observatory
.
The CLFST has made three astronomical catalogues of the Northern Hemisphere:
Aperture synthesis
Aperture synthesis or synthesis imaging is a type of interferometry that mixes signals from a collection of telescopes to produce images having the same angular resolution as an instrument the size of the entire collection...

- 6CSixth Cambridge Survey of radio sourcesThe 6C Survey of radio sources is an astronomical catalogue of celestial radio sources as measured at 151-MHz. It was published between 1985 and 1993 by the Radio Astronomy Group of the University of Cambridge....
survey at 151 MHz - 7CSeventh Cambridge SurveyThe 7C Survey of radio sources was performed by the Cavendish Astrophysics Group using the Cambridge Low-Frequency Synthesis Telescope at Mullard Radio Astronomy Observatory....
survey at 151 MHz - 8CEighth Cambridge SurveyThe 8C Survey or Rees 38 MHz survey is an astronomical catalogue of celestial radio sources as measured at 38 MHz. It was published in 1990 by the Radio Astronomy Group of the University of Cambridge. Sources are labelled 8C HHMM+DDd where HHMM is the Right Ascension in hours and...
