Image data (left), best-fitting exponential models (middle), and residuals (right) in the F606W (top) and F814W (bottom) bands. We labeled the galaxy center (black open circle), along with the transient position measured from VLBA (red cross) and e-MERLIN (blue plus). The VLBA position is R.A. = 01^h55^m23﹩\mathop{.}\limits^{{\rm{s}}}﹩4323, decl. = ﹩+0{5}^{\circ }5{6}^{{\rm{{\prime} }}}17\mathop{.}\limits^{{\unicode{x02033}}}798﹩ with a 1σ uncertainty of (4.9, 1.5) mas in R.A. and decl., respectively. The e-MERLIN position is R.A. = 01^h55^m23﹩\mathop{.}\limits^{{\rm{s}}}﹩4325, decl. = ﹩+0{5}^{\circ }5{6}^{{\rm{{\prime} }}}17\mathop{.}\limits^{{\unicode{x02033}}}774﹩ with an uncertainty of (9, 3) mas.
