Abstract
We have used multi-frequency follow-up observations of a sample of extragalactic sources from the 9C survey at 15 GHz to make deductions about the expected source population at higher radio frequencies, such as those in the lower frequency bands of the Planck Surveyor satellite. In particular, we have made empirical estimates of the source counts at 22 GHz, 30 GHz, 43 GHz and 70 GHz and compared these with both known data and current theoretical predictions. We have also made an estimate of the count at the ALMA frequency of 90 GHz, with a view to assessing the possible population of point sources available for the phase calibration of that instrument.
