Positions of radio images observed by KaVA and the lens model predictions. The positions of the images are referenced to the lensed image A (0,0). Position errors are estimated based on the scatter of fitted positions based on the assumption that all of the components are stationary. The positions (RA, Dec.) are shown for the observed lensed images A and B for the core and jet components. The image A was modelled by 4 Gaussians (core, main jet, left wing, right wing). The lensed image B was modelled by 2 Gaussians (core, jet). Table reports averaged positions over five epochs (2017 Nov 12, 2018 Jan 05, 2018 Nov 12, 2018 Nov 28, 2018 Dec 24). The ΔMODEL represents a difference between the predicted and observed positions of the lensed images, as well as reconstructed positions of the core and jet in the source plane in respect to the lens centre. Table also shows time delays, magnifications, and magnification rations predicted using the best SIS lens model.
