Abstract:
As one part of a program to detect complete samples of active
extragalactic objects, the 3.36x10-3sr field centered on
alpha=12h04min, delta=+11deg30' (1950.0) was mapped with the Very
Large Array at 1411MHz. Sixty-seven maps cover this field so that no
point is more than 15arcmin from the nearest map center. The median
map noise is 0.6mJy, and the 6sigma completeness limit is less than
6mJy over half of the survey field. The synthesized point-source
response is an elliptical Gaussian 22x18arcsec between half-intensity
points. The rms source-position uncertainties are ∼1arcsec in each
coordinate so that reliable optical identifications can be made on the
basis of radio-optical position coincidence alone. The sky density of
sources with flux densities 5≤S<150mJy and the angular-size
distribution of sources between 30 and 150mJy were determined.
