Doppler delay of 30 pulse trains due to the circular orbit of the pulsar around the companion. The circles represent our 30 data points, and the dotted line represents the delays for a circular orbit with the best‐fitting parameters of P₀ = 13.502932 ± 0.000012 s, a_X sin i = 26.94 ± 0.29 lt‐sec, T_ec = JD 2,448,559.3592 ± 0.0016, and the orbital period fixed to P_orb = 1﹩\fd﹩40839. The bottom panel represents the residuals (in seconds) between the data points and the dotted line.
