Conclusions

• The INTEGRAL and Swift data are essential in
  showing the connection between the prompt
  readiation and the afterglow.
• Both in GRB 031203 and in GRB 050315 the prompt
  emission appears to be the peak of the
  afterglow.
• The essential continuity between the prompt
  radiation and the afterglow is evidences by the
  monotonic variation of the instantaneous spectrum
  in GRB 031203. We are currently developing this
  important tool in the case of GRB 050315.
