Table 4: Delays between the event time and the event time tag (reconstructed for SPI) for the high energy instruments. The positive delay should be added to the event OBT time tag to get the absolute event time. The delay was calibrated on ground and measured in-flight comparing INTEGRAL and RXTE Crab light curves in absolute phase.

**Table 4:** Delays between the event time and the event time tag (reconstructed for SPI) for the high energy instruments. The positive delay should be added to the event OBT time tag to get the absolute event time. The delay was calibrated on ground and measured in-flight comparing *INTEGRAL* and *RXTE* Crab light curves in absolute phase.
