ARKS continuum clean images of the eight systems in the sample with background sources before their subtraction. The data were imaged with a robust value of 2 and the white ellipse in the bottom left corner represents the corresponding beam. The grey ellipses represent the best-fit location and size (FWHM) of the SMGs at the different epochs of observations. For HD 95086 the image has a non-linear scale to increase the dynamic range and to visualise both SMGs. The white minor and major ticks in all panels are spaced by 2″ and 10″, respectively.
