Post-fit timing residuals of PSR J1910−5959A as a function of time and orbital phase using the ELL1 binary model. The first and second rows show the data from the 64 m Parkes Murriyang radio telescope and the MeerKAT radio telescope, respectively. The different receiver and backend combinations mentioned in Table 1 are denoted with different colours and symbols, respectively. The panels at the very bottom provide the combined dataset, with the ToAs that have uncertainties greater than 8 μs made semi-transparent for clarity.
