This Event Table shows the telecomand status of the WHISPER sounder on the Cluster-4 spacecraft when passive (i.e., when measuring natural plasma waves)
For each time interval, the following information is provided : 
    time_tags__C1_CT_WHI_NATURAL_EVENT : The time interval
    fft_size__C1_CT_WHI_NATURAL_EVENT : The number of frequency bins of the Fast Fourier Transform
    Receiving_Antenna__C1_CT_WHI_NATURAL_EVENT : The receiving antenna used, Ey or Ez
    Average_Number__C1_CT_WHI_NATURAL_EVENT : The number of averaged individual spectra. Individual spectra are produced at the rate of one every 13.33 ms
    Gain_Command__C1_CT_WHI_NATURAL_EVENT : The gain command number
        0 : fixed gain +12 dB
        1 : fixed gain +24 dB
        2 : fixed gain +36 dB
        3 : fixed gain +36 dB
        4 : automatic gain +24/+12 dB
        5 : automatic gain +24/+12 dB
        6 : automatic gain +36/+24 dB
        7: automatic gain +36/+24 dB)
    Averaged_Spectrum_Select_Rate__C1_CT_WHI_NATURAL_EVENT : Output rate of the averaged spectra
    Energy_Overflow_Averaging_Flag__C1_CT_WHI_NATURAL_EVENT : 
        Averaging status: 
            0 : OFF
            1 : ON 
    Compression_Methode_Required__C1_CT_WHI_NATURAL_EVENT:
         0 if the exponent size is adjusted 
         1 if the exponent size is fixed to 5
    Compressed_Data_Size__C1_CT_WHI_NATURAL_EVENT :
        Compressed data size: 
            0 means 8 bits, 
           1 means 6 bits
