Details

In the Dim column, N indicates the number of whistler events contained in the data file, m the number of points of the corresponding time-series, n the number of points of the corresponding PSD, p the number of frequencies of the PSD

Flags is stored as a 8 bits unsigned integer and can nominally take values from 0 to 15. This number can be written in a binary form such as Flags = '0000abcd', where:

  • ‘a’ stands for Flag_outlier value,
  • ‘b’ stands for Flag_magnetic_condition value,
  • ‘c’ stands for Flag_heater value,
  • ‘d’ stands for Flag_step value.
