Extract

Figure 1 shows the spectrum of 3C279 (1253-05) in mid-1966 derived from observations at frequencies of 467, 630, 960, 1410, 2650 and 5000 MHz made by Batchelor, Brooks, Cooper, Milne, Roberts and the author with the CSIRO 210 ft. telescope. The figure also shows the spectrum obtained in 1964 by Kellermann with the same telescope. All the flux densities have been measured relative to a number of calibration sources on a scale previously determined by Kellermann. Although our flux densities are preliminary, further analysis should not change them significantly.
