Residuals of Uranus positions by this work with respect to DE442. The 300 s and 500 s exposed images are represented by cyan and blue circles. There are also other ephemerides plotted in the figure to show the difference from DE442+D7M25. Residuals along R.A. (Δα^∗) and decl. (Δδ) are shown in upper and lower panels, respectively. The “*” in Δα^∗ means multiplication by the cosine of the decl.
