摘要：

Soft Gamma-ray Repeaters exhibit pulse profile changes in connection with their burst activity. We present the first detailed history of the pulse profile evolution of two SGRs using a large set of RXTE/PCA observations spanning similar to5 years, and we examine their evolution with energy. This study allows us to investigate the burst induced changes of the pulse profiles, and the pulsed count rates (proportional to the pulsed X-ray intensity) during the burst activity or in quiescence.
