Diameters of Some Quasars at a Wavelength of 66.9 cm


THE measurement of the diameter of radio sources in the range of 10−2 sec of arc or less has recently been made possible by a new technique in radio interferometry. Independent stable local oscillators are used to convert the signals at the two stations to frequencies which are recorded on magnetic tapes. In principle, these long baseline interferometers… (More)
