Comment on J0513-2159 . Our image shows an extension to about 5 mas SE from the brightest feature. The EVN 8 GHz image by Dallacasa et al. (1998), with about five times larger resolution, shows an extension from the brightest feature roughly opposite to our direction. As noted by Dallacasa et al. (1998), the structure detected has a highly inverted spectrum, which, together with the reported variability in the source, could explain the structural disagreement. ...
