Spectrogram of the VLF EField (1-8kHz, 1 component, Postscript) in survey mode

The DEMETER experiments are described in the special issue of Planetary and 
Space Science published in April 2006. 
We recommend the data users to contact the PI of the corresponding experiment 
early in their study. 

An example of acknowledgments could be:
This work is based on observations with ICE, IMSC, RNF, IAP, IDP and ISL instruments embarked on
the satellite DEMETER launched by CNES (Centre National d'Etudes Spatiales).
The author thanks J.J. Berthelier, M. Parrot, J.A. Sauvaud, J.P. Lebreton and J.L. Pinçon, PI's of 
these instruments for the use of the data, and CDPP (Centre des Données de la Physique des Plasmas) 
for the provision of these data.
