This Event Table shows the telecomand status of the WHISPER sounder on the Cluster-2 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 +12dB
    1:fixed gain +24dB
    2:fixed gain +36dB
    3:fixed gain +36dB
    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
