Caption: Figure 9.
Predicted pulsar spin-period variations along the outer orbit based on the timing solution A. The orbital phase is defined as the mean anomaly measured from ω2. The FAST observational time span occupies only a small fraction of the outer orbit, indicated by the magenta line. The Fermi data span is indicated by the thick gray line.
