VLA 15 GHz (2 cm) radio maps of four typical compact galaxies in the survey (NGC 5485, NGC 6482, NGC 6340, and NGC 6703). The remaining sources (NGC 4051, NGC 1055, NGC 5273, NGC 6951, and NGC 4395) plotted here are the only five detections with extended emission. The rms noise for individual maps are 13.1, 9.0, 10.2, 9.2, 12.3, 10.6, 12.0, 11.2, and 11.1 μ Jy beam−1, respectively. The lowest-level contours are at 3σ rms noise for each source, while the subsequent contours are obtained at 3σ rms noise multiplied by integer powers of 2.5. The dashed lines represent the negative contours (which show the −3σ rms noise).
