Notes. Our TEMPONEST timing analysis makes use of the JPL DE438 Solar System ephemeris and the TCB timescale. For the measured timing parameters, the numbers in parentheses represent the 1σ uncertainty taken as the 68% confidence levels around the median value for the posterior of each parameter. As the TN is not constrained, we report the 95% confidence upper limit for the amplitude, . The rms residuals are computed after subtraction of the DM model.
