As part of the VLA calibration program, 404 small angular size sources have been observed in the “A” array at both 6 and 20 cm with resulting resolutions of 0.4′ and 1.2′ respectively. Use of self-calibration techniques has allowed a search for associated extended structure to a level of ∼0.3% of the peak. Here we report preliminary analysis of the results.
