  : 9 GHz ATCA observations of SNR 1987A used for imaging. The radius listed is that obtained by fitting a thin spherical shell to each $u-v$ data-set (see text).[]{data-label="tab_9ghz"}

The resulting series of images are shown in Figures \[fig\_movie\_natural\] and \[fig\_movie\_super\] under the conditions of diffraction-limited resolution and super-resolution, respectively. In these figures and Figure \[fig\_models\], the R.A. and Dec. offsets are with respect to J2000 R.A. $05^{\rm h}\;35^{\rm m}\;28\fs00$, Dec. $-69^{\circ}\;16'\;11\farcs1$ The diffraction-limited images indicate that the source is clearly extended, primarily in the east-west direction, and continues to brighten. In the super-resolved sequence of images, it can be seen that the shell-like morphology reported by Staveley-Smith et al. (1993a) and by
