Noise-free simulations of isolated cores with FWHM0 = 5, 15, 30, and 70 arcsec (left to right). The first row shows the synthetic reference images used as input for the simulations (panel A). The rows below display the results for different methods of data combination. ALMA 12 m-alone (panel B), ALMA 12 m + 7 m (panel C), ALMA Feather (panel D), ALMA MACF (panel E), and ALMA 12 m + IRAM-30 m MACF (panel F), shown form top to bottom. The size of each image is 2.8 arcmin × 2.8 arcmin.
