Continuum map at 0.86 mm of the NGC 613 (left) and NGC 1672 (right) nucleus. The spatial scale is RA-Dec offset in arcsec from the central position of Table 1. The color scale is in milliJansky beam⁻¹. The first contour is at 2σ, and the next contours are spaced by 1σ (see Sect. 4.1 for the value of σ). The AGN center is indicated by a black cross, and the bar at bottom left is 1 pc long. A red arrow indicates the jet direction in NGC 613.
