\caption{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 \INT\ and {\it RXTE}
Crab light curves in absolute phase.}
