Comparison of Hubble and expected Rubin Observatory LSST data resolution. (L) BVz color image from the Hubble CANDELS field with θ = 0.1” and r ≈ 28.5. Roman will have comparable resolution. (R) Simulated Rubin LSST image made by degrading Hubble data to Rubin resolution of θ = 0.6”. In the Rubin image, the galaxy is blended with surrounding objects. Correlating overlapping Rubin and Roman imagery would make it possible to develop machine learning algorithms to deblend Rubin imagery that does not overlap with Roman.
