The 9C Survey: a deeper source count at 15 GHz
Abstract
Description
Foreground radio sources are a major contaminant for centimetre-wave cosmic microwave background (CMB) measurements and the 9C survey was set up as part of the observing strategy of the CMB telescope, the Very Small Array. Prior to this survey with the Ryle Telescope at 15 GHz there was no comparable high-frequency radio survey of any extent. Our first published source count reached a limit of ~25mJy but we have now surveyed some areas more deeply, to a completenesss limit of ~5mJy. We present the results from this deeper survey.
