CLU3 WHISPER Event information under natural mode

This Event Table shows the telecomand status of the WHISPER sounder on the Cluster-3 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
