cds-question@unistra.frradio-sourcesThree selected fields were observed with the Very Large Array (VLA) at 1411MHz as part of an ongoing project to compile complete samples of active extragalactic objects. The radio-source list for the field "A" centered on alpha=08h54m, delta=+17d30' is presented. 67 maps cover the area 3x3deg so that every point lies within at least one primary half-power beamwidth. The median map noise is 0.5mJy and the 6{sigma} completeness level is less than 6mJy over half the field. The synthesized point-source response is an elliptical Gaussian approximately 20x17" between half-intensity points. The areal density of sources with flux densities in the range 5<S<150mJy was determined. Optical identifications based on position coincidences with 90 objects brighter than B=~21.5 in the A and B survey fields are reported.1985AJ.....90.1437Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/90/1437CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/87/739 : Active Extragalactic Objects I.
