The 110 GHz continuum of NGC 4194 overlaid on an HST WFPC2 image. The contours are: 0.9 × (−3,3,4,5) mJy beam-1. Rms in the map is 1 mJy beam-1 thus the first contour is at 2.7σ. The peak flux density is 4.6 mJy beam-1. The cross marks the position of the 1.4 GHz continuum (Condon et al. 1990). Hatched ellipse indicate beam size and orientation.
