Notes. Column 1: name of subcomponent; Col. 2: observing frequency; Col. 3: flux density and uncertainty; Cols. 4 and 5: relative image positions to α = 01 : 31 : 13.494, 
(J2000), extended by the components for image B as read off Fig. 6 in Biggs et al. (2004). We assumed an uncertainty of 0.1 mas for all subcomponent positions of images A, C, and D and estimated an uncertainty of 1 mas for the subcomponent positions of image B; Col. 6: extension of semi-major axis of elliptical Gaussian fitted by OMFIT; Col. 7: axis ratio of semi-minor to semi-major axis; Col. 8: position angle measured from north to east.
