RXTE-PCA (blue), Swift-XRT (red), and Suzaku-XIS3 pulse profiles (green). The profiles are folded on the first time bin of the extracted XIS3 light curve (MJD 54 434.4819). Owing to a comparable sensitive energy range the profiles as detected by Swift-XRT (0.2–10 keV) and Suzaku-XIS3 (0.2–12 keV) are similar in shape, while the secondary peak is much more prominent at higher energies as seen in RXTE-PCA (2–60 keV). To show the good agreement between the Swift and Suzaku data, profiles are shown with 64 bins instead of the 32 bins used for the arrival time analysis.
