Radio positions from the ICRF3 in the S/X, K, and X/Ka bands and the Gaia position for source 1157-215, on its radio images at 8.7 GHz from Astrogeo (left) and at 15.3 GHz from MOJAVE (right). Overlay contours are shown at levels of peak percentage, specified at the bottom of the plot. Since these radio images do not have information regarding the absolute positions, the peaks are formally assumed to be located in the S/X-band positions. Error bars are the uncertainties from the four catalogs. The K- and X/Ka-band positions are the ones after the full deformation transformations (Charlot et al. 2020). The angular separations of the K- and X/Ka-band positions and the Gaia position relative to the S/X-band position for this source are 2.29 ± 0.31 mas, 3.54 ± 0.32mas, and 3.97 ± 0.13 mas, respectively.
