ZCB This set of AMPTE-IRM data came from the University of Iowa single-channel digitized waveform file. Each file (table) contains plasa waves measured in the frequency range from quasi-dc to 5 MHz and occurring in an integral one minute interval. Each record (row) contains a 10 millisecond waveform series. Please acknowledge the AMPTE IRM team, University of Iowa, and the National Space Science Data Center.
