Difference in the position of S2 obtained from an analysis with and without the aberration corrections. Colored dots indicate the epoch-wise mean for different realizations of the phase- and amplitude-maps, and gray dots show the results for individual observations. From these, we determine a mean position correction as a function of time with a corresponding upper and lower limit as indicated by the solid black line and the gray band. The thin dashed line finally represents the correction applied in Gravity Collaboration (2019).
