J. 87 739 1982 1982AJ.....87..739C Radio sources As one part of a program to detect complete samples of active extragalactic objects, the 3.36x10^-3^sr field centered on alpha=12h04mim, 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.
