. Comment on J0431+2037 . A Gigahertz Peaked Spectrum (GPS) galaxy with complex radio structure on the scale of 10 to 100 mas (combined EVN+MERLIN data at 1.6 GHz, Dallacasa et al. 1995). Our image is consistent with the center-southern features of Dallacasa et al. (1995). The northern feature, ~180 mas N-NW from the field center, outside the boundary of the displayed image, can barely be seen in our data. VLBApls home page . Last modified: 16 Oct 2000
