J/AJ/98/1148 VLA survey of 0016+16, Abell 665, and Abell 2218 (Moffet+, 1989)
A VLA survey of the 3 clusters of galaxies 0016+16, Abell 665, and Abell 2218. Moffet A.T., Birkinshaw M. <Astron. J. 98, 1148 (1989)> =1989AJ.....98.1148M (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, galaxy ; Galaxies, radio Description: We have used the VLA to survey the fields of the three clusters of galaxies; 0016+16, Abell 665 (0826+66) and Abell 2218 (1635+66) at 1440 MHz, 4860 MHz, and 14940 MHz (for the brighter sources). The survey was aimed at finding radio sources which might contaminate the Sunyaev-Zel'dovich effect. We have detected 86 sources in these three clusters and examined Palomar sky survey prints for possible optical identifications. File Summary:

Note (1): These columns give the name of the cluster which contains the source and the number of the source within the field. The sources are numbered independently for each of the 3 clusters. Note (2): These columns give the B1950 position of the source The positions were combined from measurements at each frequency, taking account of possible systematic, frequency-dependent errors in the locations of the radio centroids. Where the source was clearly resolved, the center of the radio emission (either the location of a point source, or the midpoint of extended lobes) was used for the source position. Note (3): flagged with a "<" when the corresponding flux densities are upper limits. Note (4): These columns give the flux density at 1440 MHz, 4860 MHz, and 14940 MHz, in mJy. The flux density scale is that of Baars, et. al (1977A&A....61...99B). It is important to note that these fields were not systematically observed at 15 GHz; only the strongest sources were targeted at that frequency. Note (5): These columns are flagged with a "<" when the corresponding major and minor axes sizes are upper limits. Note (6): These columns give the angular size and position angle of the sources. The major and minor axes are listed independently, in arcsec, and the position angle is listed in degrees. Note (7): This column gives radio and optical comments on the source, separated by a semi-colon where both are given. Where reference is made to a figure, the original paper listed that reference in the angular size column and this reference has been moved to the comments column for the electronic version of this catalogue. See the published paper for the figures. Note (8): These columns give the B1950 position and error of the optical candidate of the source.
History: "The catalogue was originally archived as A010 by H. Andernach () and the ADS documentation prepared in collaboration with Carolyn Stern Grant ()."
