Baryon model. Left panel: 2018 HST data in the F814W band (slightly smoothed and to the power 1/2 to increase the detail at larger radii). The circle on top of the Einstein ring has 0.3″ radius. Middle panel: merged F814W + F160W image. The yellow circles mark the region where the two images are weighted and combined. Right panel: baryon model based on a combination of images in the F160W and F814W bands and after subtracting the background galaxy. For reference, we overlay the 0.3″ radius circle marking the position of the Einstein ring.
