INTEGRAL probes the morphology of the Crab nebula in hard X-rays/soft gamma-rays

Aims. We use the IBIS/ISGRI telescope on-board INTEGRAL to measure the position of the centroid of the 20-200 keV emission from the Crab region. Methods. We find that the astrometry of the IBIS telescope is affected by the temperature of…
