Comparison of the observed energy resolved pulse profiles of V 0332+53 (observation with OBS ID=80102002010 and a luminosity value of (5.3 – 14)·10³⁶erg·s⁻¹) and their Fourier fits at different energy bands. Left: Normalized pulse profiles of V 0332+53 (observation with OBS ID=80102002010 and a luminosity value of (5.3 – 14)·10³⁶erg·s⁻¹) at different energy ranges based on NuSTAR data. The measured profiles are represented by solid lines, whereas the Fourier fits are represented by dashed lines. The boundaries of the energy ranges are [3, 6, 12, 15, 27.6, and 78] keV. Right: Overall approximate pulse profile (black solid line) and Fourier components 1–5 (coloured dashed lines: blue, red, green, purple, and yellow, respectively).
