Comparison of the normalized pulse profiles of different sources of the sample studied at different energy ranges. The sources are in order from left to right: Vela X–l (type 2), GX 301 – 2 (type 2), CenX–3 (type 1), 1E1145.1–6141 (type 1), LMC X–4 (typeO), and IGR J16393–4643 (type 0). The measured profiles are represented by solid lines, whereas the Fourier fits are represented by dashed lines. The boundaries of the energy ranges are [0.5, 3, 6, 12, 15, 27.6, and 78] keV. The pulse profiles were phase shifted by hand to align the maximums of the pulse profiles of two observations (in cases with observations of both telescopes) and coloured according to their respective pulse profile types in order to better show a comparison between them.
