Update of the posterior analysis of Gravity Collaboration (2018a). The panels show the residuals of the radial velocity data to the best-fit orbit in which post-fit the redshift and transverse Doppler effect were turned off (line at 0, f_redshift = 0). The 2018 data show a highly significant excursion. The red line gives the orbit with f_redshift = 1. General relativity is an excellent description for the residuals.
