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^-3^sterad. 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
