The Crab nebula and pulsar were observed by INTEGRAL in February for
calibration purposes. An important goal of these observations is a
proper calibration at high energies. Observations of the Crab pulsar
(pulse period 33 ms) can also be used for timing calibration
purposes. The picture shows the pulse profile of the Crab pulsar
obtained with IBIS in various energy bands.
