IGR J11215−5952 pulse profile folded on the spin period of 187 s, assuming MJD 57432 as epoch of phase zero. The whole NuSTAR exposure time has been considered. From top to bottom: soft profile (S = 3−12 keV), hard one (H = 12−78 keV), their hardness ratio (H/S) and profile in the total band (S+H = 3−78 keV), respectively. Each pulse profile has been normalised by dividing by the average source intensity in the considered energy band.
