摘要:Conversational spectral analysis program (CSAP) system is apphed to the simultaneous magnetlc pulsation data of November 17, 1976 when various kinds of ULF penomena were observed at Syowa and Mizuho Stations. In this paper, the analysis procedure, the outline of the CSAP system with graphic display terminal and analysis results are shown and discussed. The results show that the CSAP system is useful for studying magnetic pulsation data.
