Data Access
This dataset contains electric field power spectral density measured on Cluster-2 by WHISPER when the sounder is active.
Each data record contains the following support parameters :
Interval centred time tag
Receiving antenna used, Ey or Ez
Spectral Frequencies between 1.953 and 79.915 kHz, that is, the frequencies corresponding point to point to the 512 elements of the fixed size spectrum
Frequency Swept Table Number between 0 and 127
Time interval between two successive emission pulses in units of 40/3 (= 13.3) ms :
0: 1 unit (13.3 ms)
1: 2 units (26.6 ms)
2: 3 units (40 ms)
3: 5 units (66.6 ms)
4: 8 units (106.6 ms)
5: 40 units + 2106.66 ms waiting + 256 units + 2446.66 ms waiting (8.5 s)
6: 6 units + 45 ms waiting (125 ms)
7: 14 units + 63.34 ms waiting (250 ms)
Delay between the leading edge of the emission pulse and the starting edge of the associated reception (acquisition time interval)
Number of gain changes during the acquisition
First part of the compressed value which is a fixed point integer defined in the compression algorithm
