Notes. The results are obtained from our TEMPONEST outputs of the TEMPO2 T2 binary model. Derived orthometric Shapiro delay and ELL1 timing parameters are also computed for reference. All uncertainties in the measured values are 68.3 % confidence limits.
Ω and i, should be read within the context of Sect. 4.3.1.
