Scientific paper

New 6-cm VLA maps with a 1-2 arcsec resolution are presented, in conjunction with data from the literature, for a sample of 91 cD galaxies in Abell clusters; an effort is made to determine the possible effects of global and local cluster properties on the radio properties of cDs, where the dominant predictor is the presence of X-ray cooling flows. There is a weak correlation between radio power and the ellipticity of the cD at 16 kpc from the galaxy's optical center. The radio morphological types of the detected galaxies are related to radio luminosity and spectral index; compact radio sources are most often detected.
