Follow-up observations at 16 and 33GHz of extragalactic sources from WMAP 3-yr data: II - Flux density variability
Using the Arcminute Microkelvin Imager (AMI) at 16GHz and the Very Small Array (VSA) at 33GHz to make follow-up observations of sources in the New Extragalactic WMAP Point Source catalogue, we have investigated the flux density variability in a complete sample of 97 sources over time-scales of a few months to ~1.5yr. We find that 53 per cent of the
