Fig. 1
Observed pulse frequency modulated by orbital motion as measured with (left to right) Fermi GBM, RXTE and EXOSAT, and Tenma during the three major outbursts from the source. Reconstructed intrinsic pulsar frequencies (black dashed lines) modulated by motion along the orbit with best-fit parameters (red line) together with fit residuals are also shown.
