Kinematical maps for objects SSA22A-M38, SSA22A-C16, CDFS-2528 and SSA22A-D17 (from the top respectively). Respectively, from the left: flux, velocity and sigma map. the X − Y coordinates are in arcseconds referred to an arbitrary object center position. The north direction is the positive Y axis. The vertical color bars are in arbitrary units for the flux map and in km s^-1 for the velocity and sigma maps. Overplotted on the flux map the continuum flux distribution (brown isophotes) for the object whenever we detect a continuum flux component with sufficient S/N.
