Description:

The 10C survey of radio sources is being made with the Arcminute Microkelvin
Imager (AMI) Large Array at 15.7 GHz and a resolution of approximately 30
arcsec. The regions surveyed correspond to the fields chosen for the CMB
observations of the AMI Small Array. The survey fields cover an area of
~ 27 deg^2 complete to ~ 1.0 mJy. Results for some deeper areas, covering
~ 12 deg^2, wholly contained within the total areas and complete to 0.5 mJy
are also included. The source catalogue contains a total of 1897 sources.

Areas complete to ~1.0 mJy apart from exclusion zones listed below:

The completeness in both cases is estimated to be at least 93 per cent. The
position accuracy is estimated to be better than 10 arcsec.

Note (1):
Source type:
'P' point source
'E' extended source

Note (2):
Flag:
'*' indicates that the point-source response could not be well approximated
as an elliptical Gaussian and that therefore the results from the
Gaussian-fitting must be treated with caution

Note (3):
Region:
'D' deep region
'S' shallow region
'N' otherwise
