Abstract:
Eleven selected regions of sky have been surveyed at an observing
frequency of 4.85GHz to limiting flux densities as low as 0.01Jy. The
surveys provide a sample of 118 sources for source counts from a solid
angle of 7.14x10-3sterad. The resulting counts are in excellent
agreement with those from a previously surveyed region. The combined
counts show a smooth convergence below a flux density of about 0.15Jy
and indicate that the convergence becomes steeper below a flux density
of 0.02Jy. No evidence for anisotropy is found.

Note (1): 1: Source lies just outside survey boundary;
not included in source counts
2: Source flux density is below limiting flux density for
survey zone, but source was detected in at least two
adjacent scans. Not included in source counts
